Get aliases Generally available

GET /_cat/aliases/{name}

All methods and paths for this operation:

GET /_cat/aliases

GET /_cat/aliases/{name}

Get the cluster's index aliases, including filter and routing information. This API does not return data stream aliases.

IMPORTANT: CAT APIs are only intended for human consumption using the command line or the Kibana console. They are not intended for use by applications. For application consumption, use the aliases API.

Required authorization

  • Index privileges: view_index_metadata

Path parameters

  • name string | array[string]

    A comma-separated list of aliases to retrieve. Supports wildcards (*). To retrieve all aliases, omit this parameter or use * or _all.

Query parameters

  • h string | array[string]

    A comma-separated list of columns names to display. It supports simple wildcards.

    Supported values include:

    • alias (or a): The name of the alias.
    • index (or i, idx): The name of the index the alias points to.
    • filter (or f, fi): The filter applied to the alias.
    • routing.index (or ri, routingIndex): Index routing value for the alias.
    • routing.search (or rs, routingSearch): Search routing value for the alias.
    • is_write_index (or w, isWriteIndex): Indicates if the index is the write index for the alias.

    Values are alias, a, index, i, idx, filter, f, fi, routing.index, ri, routingIndex, routing.search, rs, routingSearch, is_write_index, w, or isWriteIndex.

  • s string | array[string]

    List of columns that determine how the table should be sorted. Sorting defaults to ascending and can be changed by setting :asc or :desc as a suffix to the column name.

  • expand_wildcards string | array[string]

    The type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. It supports comma-separated values, such as open,hidden.

    Supported values include:

    • all: Match any data stream or index, including hidden ones.
    • open: Match open, non-hidden indices. Also matches any non-hidden data stream.
    • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
    • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
    • none: Wildcard expressions are not accepted.

    Values are all, open, closed, hidden, or none.

  • local boolean

    If true, the request computes the list of selected nodes from the local cluster state. If false the list of selected nodes are computed from the cluster state of the master node. In both cases the coordinating node will send requests for further information to each selected node.

Get the cluster health status Generally available

GET /_cat/health

IMPORTANT: CAT APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use the cluster health API. This API is often used to check malfunctioning clusters. To help you track cluster health alongside log files and alerting systems, the API returns timestamps in two formats: HH:MM:SS, which is human-readable but includes no date information; Unix epoch time, which is machine-sortable and includes date information. The latter format is useful for cluster recoveries that take multiple days. You can use the cat health API to verify cluster health across multiple nodes. You also can use the API to track the recovery of a large cluster over a longer period of time.

Required authorization

  • Cluster privileges: monitor

Query parameters

  • time string

    The unit used to display time values.

    Values are nanos, micros, ms, s, m, h, or d.

  • ts boolean

    If true, returns HH:MM:SS and Unix epoch timestamps.

  • h string | array[string]

    List of columns to appear in the response. Supports simple wildcards.

  • s string | array[string]

    List of columns that determine how the table should be sorted. Sorting defaults to ascending and can be changed by setting :asc or :desc as a suffix to the column name.

Get configuration and usage information about transforms.

CAT APIs are only intended for human consumption using the Kibana console or command line. They are not intended for use by applications. For application consumption, use the get transform statistics API.

Required authorization

  • Cluster privileges: monitor_transform

Path parameters

  • transform_id string Required

    A transform identifier or a wildcard expression. If you do not specify one of these options, the API returns information for all transforms.

Query parameters

  • allow_no_match boolean

    Specifies what to do when the request: contains wildcard expressions and there are no transforms that match; contains the _all string or no identifiers and there are no matches; contains wildcard expressions and there are only partial matches. If true, it returns an empty transforms array when there are no matches and the subset of results when there are partial matches. If false, the request returns a 404 status code when there are no matches or only partial matches.

Update voting configuration exclusions Generally available; Added in 7.0.0

POST /_cluster/voting_config_exclusions

Update the cluster voting config exclusions by node IDs or node names. By default, if there are more than three master-eligible nodes in the cluster and you remove fewer than half of the master-eligible nodes in the cluster at once, the voting configuration automatically shrinks. If you want to shrink the voting configuration to contain fewer than three nodes or to remove half or more of the master-eligible nodes in the cluster at once, use this API to remove departing nodes from the voting configuration manually. The API adds an entry for each specified node to the cluster’s voting configuration exclusions list. It then waits until the cluster has reconfigured its voting configuration to exclude the specified nodes.

Clusters should have no voting configuration exclusions in normal operation. Once the excluded nodes have stopped, clear the voting configuration exclusions with DELETE /_cluster/voting_config_exclusions. This API waits for the nodes to be fully removed from the cluster before it returns. If your cluster has voting configuration exclusions for nodes that you no longer intend to remove, use DELETE /_cluster/voting_config_exclusions?wait_for_removal=false to clear the voting configuration exclusions without waiting for the nodes to leave the cluster.

A response to POST /_cluster/voting_config_exclusions with an HTTP status code of 200 OK guarantees that the node has been removed from the voting configuration and will not be reinstated until the voting configuration exclusions are cleared by calling DELETE /_cluster/voting_config_exclusions. If the call to POST /_cluster/voting_config_exclusions fails or returns a response with an HTTP status code other than 200 OK then the node may not have been removed from the voting configuration. In that case, you may safely retry the call.

NOTE: Voting exclusions are required only when you remove at least half of the master-eligible nodes from a cluster in a short time period. They are not required when removing master-ineligible nodes or when removing fewer than half of the master-eligible nodes.

External documentation

Query parameters

  • node_names string | array[string]

    A comma-separated list of the names of the nodes to exclude from the voting configuration. If specified, you may not also specify node_ids.

  • node_ids string | array[string]

    A comma-separated list of the persistent ids of the nodes to exclude from the voting configuration. If specified, you may not also specify node_names.

  • master_timeout string

    Period to wait for a connection to the master node.

    Values are -1 or 0.

  • timeout string

    When adding a voting configuration exclusion, the API waits for the specified nodes to be excluded from the voting configuration before returning. If the timeout expires before the appropriate condition is satisfied, the request fails and returns an error.

    Values are -1 or 0.

    Values are -1 or 0.

  • wait_for_removal boolean

    Specifies whether to wait for all excluded nodes to be removed from the cluster before clearing the voting configuration exclusions list.

External documentation

Query parameters

  • flat_settings boolean

    If true, returns settings in flat format.

  • include_defaults boolean

    If true, also returns default values for all other cluster settings, reflecting the values in the elasticsearch.yml file of one of the nodes in the cluster. If the nodes in your cluster do not all have the same values in their elasticsearch.yml config files then the values returned by this API may vary from invocation to invocation and may not reflect the values that Elasticsearch uses in all situations. Use the GET _nodes/settings API to fetch the settings for each individual node in your cluster.

  • master_timeout string

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

    Values are -1 or 0.

Get the cluster health status Generally available; Added in 1.3.0

GET /_cluster/health/{index}

All methods and paths for this operation:

GET /_cluster/health

GET /_cluster/health/{index}

You can also use the API to get the health status of only specified data streams and indices. For data streams, the API retrieves the health status of the stream’s backing indices.

The cluster health status is: green, yellow or red. On the shard level, a red status indicates that the specific shard is not allocated in the cluster. Yellow means that the primary shard is allocated but replicas are not. Green means that all shards are allocated. The index level status is controlled by the worst shard status.

One of the main benefits of the API is the ability to wait until the cluster reaches a certain high watermark health level. The cluster status is controlled by the worst index status.

Required authorization

  • Cluster privileges: monitor,manage

Path parameters

  • index string | array[string] Required

    Comma-separated list of data streams, indices, and index aliases used to limit the request. Wildcard expressions (*) are supported. To target all data streams and indices in a cluster, omit this parameter or use _all or *.

Query parameters

  • expand_wildcards string | array[string]

    Whether to expand wildcard expression to concrete indices that are open, closed or both.

    Supported values include:

    • all: Match any data stream or index, including hidden ones.
    • open: Match open, non-hidden indices. Also matches any non-hidden data stream.
    • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
    • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
    • none: Wildcard expressions are not accepted.

    Values are all, open, closed, hidden, or none.

  • level string

    Can be one of cluster, indices or shards. Controls the details level of the health information returned.

    Values are cluster, indices, or shards.

  • local boolean

    If true, the request retrieves information from the local node only. Defaults to false, which means information is retrieved from the master node.

  • master_timeout string

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

    Values are -1 or 0.

    A boolean value which controls whether to wait (until the timeout provided) for the cluster to have no shard relocations. Defaults to false, which means it will not wait for relocating shards.

  • wait_for_status string

    One of green, yellow or red. Will wait (until the timeout provided) until the status of the cluster changes to the one provided or better, i.e. green > yellow > red. By default, will not wait for any status.

    Supported values include:

    • green (or GREEN): All shards are assigned.
    • yellow (or YELLOW): All primary shards are assigned, but one or more replica shards are unassigned. If a node in the cluster fails, some data could be unavailable until that node is repaired.

Get the pending cluster tasks Generally available

GET /_cluster/pending_tasks

Get information about cluster-level changes (such as create index, update mapping, allocate or fail shard) that have not yet taken effect.

NOTE: This API returns a list of any pending updates to the cluster state. These are distinct from the tasks reported by the task management API which include periodic tasks and tasks initiated by the user, such as node stats, search queries, or create index requests. However, if a user-initiated task such as a create index command causes a cluster state update, the activity of this task might be reported by both task api and pending cluster tasks API.

Required authorization

  • Cluster privileges: monitor

Query parameters

  • local boolean

    If true, the request retrieves information from the local node only. If false, information is retrieved from the master node.

  • master_timeout string

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

    Values are -1 or 0.

Get remote cluster information Generally available; Added in 6.1.0

GET /_remote/info

Get information about configured remote clusters. The API returns connection and endpoint information keyed by the configured remote cluster alias.


This API returns information that reflects current state on the local cluster. The connected field does not necessarily reflect whether a remote cluster is down or unavailable, only whether there is currently an open connection to it. Elasticsearch does not spontaneously try to reconnect to a disconnected remote cluster. To trigger a reconnection, attempt a cross-cluster search, ES|QL cross-cluster search, or try the /_resolve/cluster endpoint.

Reroute the cluster Generally available; Added in 5.0.0

POST /_cluster/reroute

Manually change the allocation of individual shards in the cluster. For example, a shard can be moved from one node to another explicitly, an allocation can be canceled, and an unassigned shard can be explicitly allocated to a specific node.

It is important to note that after processing any reroute commands Elasticsearch will perform rebalancing as normal (respecting the values of settings such as cluster.routing.rebalance.enable) in order to remain in a balanced state. For example, if the requested allocation includes moving a shard from node1 to node2 then this may cause a shard to be moved from node2 back to node1 to even things out.

The cluster can be set to disable allocations using the cluster.routing.allocation.enable setting. If allocations are disabled then the only allocations that will be performed are explicit ones given using the reroute command, and consequent allocations due to rebalancing.

The cluster will attempt to allocate a shard a maximum of index.allocation.max_retries times in a row (defaults to 5), before giving up and leaving the shard unallocated. This scenario can be caused by structural problems such as having an analyzer which refers to a stopwords file which doesn’t exist on all nodes.

Once the problem has been corrected, allocation can be manually retried by calling the reroute API with the ?retry_failed URI query parameter, which will attempt a single retry round for these shards.

Query parameters

  • dry_run boolean

    If true, then the request simulates the operation. It will calculate the result of applying the commands to the current cluster state and return the resulting cluster state after the commands (and rebalancing) have been applied; it will not actually perform the requested changes.

  • explain boolean

    If true, then the response contains an explanation of why the commands can or cannot run.

  • metric string | array[string]

    Limits the information returned to the specified metrics.

  • retry_failed boolean

    If true, then retries allocation of shards that are blocked due to too many subsequent allocation failures.

  • master_timeout string

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

    Values are -1 or 0.

  • timeout string

    Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.

    Values are -1 or 0.

    Defines the commands to perform.

    Hide commands attributes Show commands attributes object
    • cancel object

      Cancel allocation of a shard (or recovery). Accepts index and shard for index name and shard number, and node for the node to cancel the shard allocation on. This can be used to force resynchronization of existing replicas from the primary shard by cancelling them and allowing them to be reinitialized through the standard recovery process. By default only replica shard allocations can be cancelled. If it is necessary to cancel the allocation of a primary shard then the allow_primary flag must also be included in the request.

    • allocate_replica object

      Allocate an unassigned replica shard to a node. Accepts index and shard for index name and shard number, and node to allocate the shard to. Takes allocation deciders into account.

      Hide allocate_replica attributes Show allocate_replica attributes object
      • index string Required
      • shard number Required

    • allocate_stale_primary object

      Allocate a primary shard to a node that holds a stale copy. Accepts the index and shard for index name and shard number, and node to allocate the shard to. Using this command may lead to data loss for the provided shard id. If a node which has the good copy of the data rejoins the cluster later on, that data will be deleted or overwritten with the data of the stale copy that was forcefully allocated with this command. To ensure that these implications are well-understood, this command requires the flag accept_data_loss to be explicitly set to true.

    • allocate_empty_primary object

      Allocate an empty primary shard to a node. Accepts the index and shard for index name and shard number, and node to allocate the shard to. Using this command leads to a complete loss of all data that was indexed into this shard, if it was previously started. If a node which has a copy of the data rejoins the cluster later on, that data will be deleted. To ensure that these implications are well-understood, this command requires the flag accept_data_loss to be explicitly set to true.

Reload the keystore on nodes in the cluster Generally available; Added in 6.5.0

POST /_nodes/{node_id}/reload_secure_settings

All methods and paths for this operation:

POST /_nodes/reload_secure_settings

POST /_nodes/{node_id}/reload_secure_settings

Secure settings are stored in an on-disk keystore. Certain of these settings are reloadable. That is, you can change them on disk and reload them without restarting any nodes in the cluster. When you have updated reloadable secure settings in your keystore, you can use this API to reload those settings on each node.

When the Elasticsearch keystore is password protected and not simply obfuscated, you must provide the password for the keystore when you reload the secure settings. Reloading the settings for the whole cluster assumes that the keystores for all nodes are protected with the same password; this method is allowed only when inter-node communications are encrypted. Alternatively, you can reload the secure settings on each node by locally accessing the API and passing the node-specific Elasticsearch keystore password.

Path parameters

  • node_id string | array[string] Required

    The names of particular nodes in the cluster to target.

Query parameters

  • timeout string

    Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.

    Values are -1 or 0.

Cluster - Health

Get the cluster health Generally available; Added in 8.7.0

GET /_health_report/{feature}

All methods and paths for this operation:

GET /_health_report

GET /_health_report/{feature}

Get a report with the health status of an Elasticsearch cluster. The report contains a list of indicators that compose Elasticsearch functionality.

Each indicator has a health status of: green, unknown, yellow or red. The indicator will provide an explanation and metadata describing the reason for its current health status.

The cluster’s status is controlled by the worst indicator status.

In the event that an indicator’s status is non-green, a list of impacts may be present in the indicator result which detail the functionalities that are negatively affected by the health issue. Each impact carries with it a severity level, an area of the system that is affected, and a simple description of the impact on the system.

Some health indicators can determine the root cause of a health problem and prescribe a set of steps that can be performed in order to improve the health of the system. The root cause and remediation steps are encapsulated in a diagnosis. A diagnosis contains a cause detailing a root cause analysis, an action containing a brief description of the steps to take to fix the problem, the list of affected resources (if applicable), and a detailed step-by-step troubleshooting guide to fix the diagnosed problem.

NOTE: The health indicators perform root cause analysis of non-green health statuses. This can be computationally expensive when called frequently. When setting up automated polling of the API for health status, set verbose to false to disable the more expensive analysis logic.

Path parameters

  • feature string | array[string] Required

    A feature of the cluster, as returned by the top-level health report API.

Query parameters

  • timeout string

    Explicit operation timeout.

    Values are -1 or 0.

  • verbose boolean

    Opt-in for more information about the health of the system.

  • size number

    Limit the number of affected resources the health report API returns.

Update the connector features Technical preview

PUT /_connector/{connector_id}/_features

Update the connector features in the connector document. This API can be used to control the following aspects of a connector:

  • document-level security
  • incremental syncs
  • advanced sync rules
  • basic sync rules

Normally, the running connector service automatically manages these features. However, you can use this API to override the default behavior.

To sync data using self-managed connectors, you need to deploy the Elastic connector service on your own infrastructure. This service runs automatically on Elastic Cloud for Elastic managed connectors.

Path parameters

  • connector_id string Required

    The unique identifier of the connector to be updated.

Create or update auto-follow patterns Generally available; Added in 6.5.0

PUT /_ccr/auto_follow/{name}

Create a collection of cross-cluster replication auto-follow patterns for a remote cluster. Newly created indices on the remote cluster that match any of the patterns are automatically configured as follower indices. Indices on the remote cluster that were created before the auto-follow pattern was created will not be auto-followed even if they match the pattern.

This API can also be used to update auto-follow patterns. NOTE: Follower indices that were configured automatically before updating an auto-follow pattern will remain unchanged even if they do not match against the new patterns.

External documentation

Path parameters

  • name string Required

    The name of the collection of auto-follow patterns.

Query parameters

  • master_timeout string

    Period to wait for a connection to the master node.

    Values are -1 or 0.

application/json

Body Required

  • remote_cluster string Required

    The remote cluster containing the leader indices to match against.

  • follow_index_pattern string

    The name of follower index. The template {{leader_index}} can be used to derive the name of the follower index from the name of the leader index. When following a data stream, use {{leader_index}}; CCR does not support changes to the names of a follower data stream’s backing indices.

  • leader_index_patterns array[string]

    An array of simple index patterns to match against indices in the remote cluster specified by the remote_cluster field.

  • leader_index_exclusion_patterns array[string]

    An array of simple index patterns that can be used to exclude indices from being auto-followed. Indices in the remote cluster whose names are matching one or more leader_index_patterns and one or more leader_index_exclusion_patterns won’t be followed.

  • max_outstanding_read_requests number

    The maximum number of outstanding reads requests from the remote cluster.

    Default value is 12.

  • settings object

    Settings to override from the leader index. Note that certain settings can not be overrode (e.g., index.number_of_shards).

    Hide settings attribute Show settings attribute object
    • * object Additional properties
  • max_outstanding_write_requests number

    The maximum number of outstanding reads requests from the remote cluster.

    Default value is 9.

  • read_poll_timeout string

    The maximum time to wait for new operations on the remote cluster when the follower index is synchronized with the leader index. When the timeout has elapsed, the poll for operations will return to the follower so that it can update some statistics. Then the follower will immediately attempt to read from the leader again.

  • max_read_request_operation_count number

    The maximum number of operations to pull per read from the remote cluster.

    Default value is 5120.

  • max_read_request_size number | string

    The maximum size in bytes of per read of a batch of operations pulled from the remote cluster.

    One of:

    The maximum size in bytes of per read of a batch of operations pulled from the remote cluster.

  • max_retry_delay string

    The maximum time to wait before retrying an operation that failed exceptionally. An exponential backoff strategy is employed when retrying.

  • max_write_buffer_count number

    The maximum number of operations that can be queued for writing. When this limit is reached, reads from the remote cluster will be deferred until the number of queued operations goes below the limit.

    Default value is 2147483647.

  • max_write_buffer_size number | string

    The maximum total bytes of operations that can be queued for writing. When this limit is reached, reads from the remote cluster will be deferred until the total bytes of queued operations goes below the limit.

    One of:

    The maximum total bytes of operations that can be queued for writing. When this limit is reached, reads from the remote cluster will be deferred until the total bytes of queued operations goes below the limit.

  • max_write_request_operation_count number

    The maximum number of operations per bulk write request executed on the follower.

    Default value is 5120.

  • max_write_request_size number | string

    The maximum total bytes of operations per bulk write request executed on the follower.

    One of:

    The maximum total bytes of operations per bulk write request executed on the follower.

Downsample an index Technical preview; Added in 8.5.0

POST /{index}/_downsample/{target_index}

Aggregate a time series (TSDS) index and store pre-computed statistical summaries (min, max, sum, value_count and avg) for each metric field grouped by a configured time interval. For example, a TSDS index that contains metrics sampled every 10 seconds can be downsampled to an hourly index. All documents within an hour interval are summarized and stored as a single document in the downsample index.

NOTE: Only indices in a time series data stream are supported. Neither field nor document level security can be defined on the source index. The source index must be read only (index.blocks.write: true).

Path parameters

  • index string Required

    Name of the time series index to downsample.

Convert an index alias to a data stream Generally available; Added in 7.9.0

POST /_data_stream/_migrate/{name}

Converts an index alias to a data stream. You must have a matching index template that is data stream enabled. The alias must meet the following criteria: The alias must have a write index; All indices for the alias must have a @timestamp field mapping of a date or date_nanos field type; The alias must not have any filters; The alias must not use custom routing. If successful, the request removes the alias and creates a data stream with the same name. The indices for the alias become hidden backing indices for the stream. The write index for the alias becomes the write index for the stream.

Required authorization

  • Index privileges: manage

Path parameters

  • name string Required

    Name of the index alias to convert to a data stream.

Query parameters

  • master_timeout string

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

    Values are -1 or 0.

  • timeout string

    Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.

    Values are -1 or 0.

Promote a data stream Generally available; Added in 7.9.0

POST /_data_stream/_promote/{name}

Promote a data stream from a replicated data stream managed by cross-cluster replication (CCR) to a regular data stream.

With CCR auto following, a data stream from a remote cluster can be replicated to the local cluster. These data streams can't be rolled over in the local cluster. These replicated data streams roll over only if the upstream data stream rolls over. In the event that the remote cluster is no longer available, the data stream in the local cluster can be promoted to a regular data stream, which allows these data streams to be rolled over in the local cluster.

NOTE: When promoting a data stream, ensure the local cluster has a data stream enabled index template that matches the data stream. If this is missing, the data stream will not be able to roll over until a matching index template is created. This will affect the lifecycle management of the data stream and interfere with the data stream size and retention.

Path parameters

  • name string Required

    The name of the data stream

Query parameters

  • master_timeout string

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

    Values are -1 or 0.

Create a new document in the index Generally available; Added in 5.0.0

POST /{index}/_create/{id}

All methods and paths for this operation:

PUT /{index}/_create/{id}

POST /{index}/_create/{id}

You can index a new JSON document with the /<target>/_doc/ or /<target>/_create/<_id> APIs Using _create guarantees that the document is indexed only if it does not already exist. It returns a 409 response when a document with a same ID already exists in the index. To update an existing document, you must use the /<target>/_doc/ API.

If the Elasticsearch security features are enabled, you must have the following index privileges for the target data stream, index, or index alias:

  • To add a document using the PUT /<target>/_create/<_id> or POST /<target>/_create/<_id> request formats, you must have the create_doc, create, index, or write index privilege.
  • To automatically create a data stream or index with this API request, you must have the auto_configure, create_index, or manage index privilege.

Automatic data stream creation requires a matching index template with data stream enabled.

Automatically create data streams and indices

If the request's target doesn't exist and matches an index template with a data_stream definition, the index operation automatically creates the data stream.

If the target doesn't exist and doesn't match a data stream template, the operation automatically creates the index and applies any matching index templates.

NOTE: Elasticsearch includes several built-in index templates. To avoid naming collisions with these templates, refer to index pattern documentation.

If no mapping exists, the index operation creates a dynamic mapping. By default, new fields and objects are automatically added to the mapping if needed.

Automatic index creation is controlled by the action.auto_create_index setting. If it is true, any index can be created automatically. You can modify this setting to explicitly allow or block automatic creation of indices that match specified patterns or set it to false to turn off automatic index creation entirely. Specify a comma-separated list of patterns you want to allow or prefix each pattern with + or - to indicate whether it should be allowed or blocked. When a list is specified, the default behaviour is to disallow.

NOTE: The action.auto_create_index setting affects the automatic creation of indices only. It does not affect the creation of data streams.

Routing

By default, shard placement — or routing — is controlled by using a hash of the document's ID value. For more explicit control, the value fed into the hash function used by the router can be directly specified on a per-operation basis using the routing parameter.

When setting up explicit mapping, you can also use the _routing field to direct the index operation to extract the routing value from the document itself. This does come at the (very minimal) cost of an additional document parsing pass. If the _routing mapping is defined and set to be required, the index operation will fail if no routing value is provided or extracted.

NOTE: Data streams do not support custom routing unless they were created with the allow_custom_routing setting enabled in the template.

Distributed

The index operation is directed to the primary shard based on its route and performed on the actual node containing this shard. After the primary shard completes the operation, if needed, the update is distributed to applicable replicas.

Active shards

To improve the resiliency of writes to the system, indexing operations can be configured to wait for a certain number of active shard copies before proceeding with the operation. If the requisite number of active shard copies are not available, then the write operation must wait and retry, until either the requisite shard copies have started or a timeout occurs. By default, write operations only wait for the primary shards to be active before proceeding (that is to say wait_for_active_shards is 1). This default can be overridden in the index settings dynamically by setting index.write.wait_for_active_shards. To alter this behavior per operation, use the wait_for_active_shards request parameter.

Valid values are all or any positive integer up to the total number of configured copies per shard in the index (which is number_of_replicas+1). Specifying a negative value or a number greater than the number of shard copies will throw an error.

For example, suppose you have a cluster of three nodes, A, B, and C and you create an index index with the number of replicas set to 3 (resulting in 4 shard copies, one more copy than there are nodes). If you attempt an indexing operation, by default the operation will only ensure the primary copy of each shard is available before proceeding. This means that even if B and C went down and A hosted the primary shard copies, the indexing operation would still proceed with only one copy of the data. If wait_for_active_shards is set on the request to 3 (and all three nodes are up), the indexing operation will require 3 active shard copies before proceeding. This requirement should be met because there are 3 active nodes in the cluster, each one holding a copy of the shard. However, if you set wait_for_active_shards to all (or to 4, which is the same in this situation), the indexing operation will not proceed as you do not have all 4 copies of each shard active in the index. The operation will timeout unless a new node is brought up in the cluster to host the fourth copy of the shard.

It is important to note that this setting greatly reduces the chances of the write operation not writing to the requisite number of shard copies, but it does not completely eliminate the possibility, because this check occurs before the write operation starts. After the write operation is underway, it is still possible for replication to fail on any number of shard copies but still succeed on the primary. The _shards section of the API response reveals the number of shard copies on which replication succeeded and failed.

Required authorization

  • Index privileges: create
External documentation

Path parameters

  • index string Required

    The name of the data stream or index to target. If the target doesn't exist and matches the name or wildcard (*) pattern of an index template with a data_stream definition, this request creates the data stream. If the target doesn't exist and doesn’t match a data stream template, this request creates the index.

  • id string Required

    A unique identifier for the document. To automatically generate a document ID, use the POST /<target>/_doc/ request format.

Query parameters

  • include_source_on_error boolean

    True or false if to include the document source in the error message in case of parsing errors.

  • pipeline string

    The ID of the pipeline to use to preprocess incoming documents. If the index has a default ingest pipeline specified, setting the value to _none turns off the default ingest pipeline for this request. If a final pipeline is configured, it will always run regardless of the value of this parameter.

  • refresh string

    If true, Elasticsearch refreshes the affected shards to make this operation visible to search. If wait_for, it waits for a refresh to make this operation visible to search. If false, it does nothing with refreshes.

    Values are true, false, or wait_for.

  • require_alias boolean

    If true, the destination must be an index alias.

  • require_data_stream boolean

    If true, the request's actions must target a data stream (existing or to be created).

  • routing string

    A custom value that is used to route operations to a specific shard.

  • timeout string

    The period the request waits for the following operations: automatic index creation, dynamic mapping updates, waiting for active shards. Elasticsearch waits for at least the specified timeout period before failing. The actual wait time could be longer, particularly when multiple waits occur.

    This parameter is useful for situations where the primary shard assigned to perform the operation might not be available when the operation runs. Some reasons for this might be that the primary shard is currently recovering from a gateway or undergoing relocation. By default, the operation will wait on the primary shard to become available for at least 1 minute before failing and responding with an error. The actual wait time could be longer, particularly when multiple waits occur.

    Values are -1 or 0.

  • version number

    The explicit version number for concurrency control. It must be a non-negative long number.

  • version_type string

    The version type.

    Supported values include:

    • internal: Use internal versioning that starts at 1 and increments with each update or delete.
    • external: Only index the document if the specified version is strictly higher than the version of the stored document or if there is no existing document.
    • external_gte: Only index the document if the specified version is equal or higher than the version of the stored document or if there is no existing document. NOTE: The external_gte version type is meant for special use cases and should be used with care. If used incorrectly, it can result in loss of data.
    • force: This option is deprecated because it can cause primary and replica shards to diverge.

    Values are internal, external, external_gte, or force.

  • wait_for_active_shards number | string

    The number of shard copies that must be active before proceeding with the operation. You can set it to all or any positive integer up to the total number of shards in the index (number_of_replicas+1). The default value of 1 means it waits for each primary shard to be active.

    Values are all or index-setting.

Get a document by its ID Generally available

GET /{index}/_doc/{id}

Get a document and its source or stored fields from an index.

By default, this API is realtime and is not affected by the refresh rate of the index (when data will become visible for search). In the case where stored fields are requested with the stored_fields parameter and the document has been updated but is not yet refreshed, the API will have to parse and analyze the source to extract the stored fields. To turn off realtime behavior, set the realtime parameter to false.

Source filtering

By default, the API returns the contents of the _source field unless you have used the stored_fields parameter or the _source field is turned off. You can turn off _source retrieval by using the _source parameter:

GET my-index-000001/_doc/0?_source=false

If you only need one or two fields from the _source, use the _source_includes or _source_excludes parameters to include or filter out particular fields. This can be helpful with large documents where partial retrieval can save on network overhead Both parameters take a comma separated list of fields or wildcard expressions. For example:

GET my-index-000001/_doc/0?_source_includes=*.id&_source_excludes=entities

If you only want to specify includes, you can use a shorter notation:

GET my-index-000001/_doc/0?_source=*.id

Routing

If routing is used during indexing, the routing value also needs to be specified to retrieve a document. For example:

GET my-index-000001/_doc/2?routing=user1

This request gets the document with ID 2, but it is routed based on the user. The document is not fetched if the correct routing is not specified.

Distributed

The GET operation is hashed into a specific shard ID. It is then redirected to one of the replicas within that shard ID and returns the result. The replicas are the primary shard and its replicas within that shard ID group. This means that the more replicas you have, the better your GET scaling will be.

Versioning support

You can use the version parameter to retrieve the document only if its current version is equal to the specified one.

Internally, Elasticsearch has marked the old document as deleted and added an entirely new document. The old version of the document doesn't disappear immediately, although you won't be able to access it. Elasticsearch cleans up deleted documents in the background as you continue to index more data.

Required authorization

  • Index privileges: read

Path parameters

  • index string Required

    The name of the index that contains the document.

  • id string Required

    A unique document identifier.

Query parameters

  • preference string

    The node or shard the operation should be performed on. By default, the operation is randomized between the shard replicas.

    If it is set to _local, the operation will prefer to be run on a local allocated shard when possible. If it is set to a custom value, the value is used to guarantee that the same shards will be used for the same custom value. This can help with "jumping values" when hitting different shards in different refresh states. A sample value can be something like the web session ID or the user name.

  • realtime boolean

    If true, the request is real-time as opposed to near-real-time.

  • refresh boolean

    If true, the request refreshes the relevant shards before retrieving the document. Setting it to true should be done after careful thought and verification that this does not cause a heavy load on the system (and slow down indexing).

  • routing string

    A custom value used to route operations to a specific shard.

  • _source boolean | string | array[string]

    Indicates whether to return the _source field (true or false) or lists the fields to return.

  • _source_excludes string | array[string]

    A comma-separated list of source fields to exclude from the response. You can also use this parameter to exclude fields from the subset specified in _source_includes query parameter. If the _source parameter is false, this parameter is ignored.

  • _source_includes string | array[string]

    A comma-separated list of source fields to include in the response. If this parameter is specified, only these source fields are returned. You can exclude fields from this subset using the _source_excludes query parameter. If the _source parameter is false, this parameter is ignored.

  • stored_fields string | array[string]

    A comma-separated list of stored fields to return as part of a hit. If no fields are specified, no stored fields are included in the response. If this field is specified, the _source parameter defaults to false. Only leaf fields can be retrieved with the stored_field option. Object fields can't be returned;​if specified, the request fails.

  • version number

    The version number for concurrency control. It must match the current version of the document for the request to succeed.

  • version_type string

    The version type.

    Supported values include:

    • internal: Use internal versioning that starts at 1 and increments with each update or delete.
    • external: Only index the document if the specified version is strictly higher than the version of the stored document or if there is no existing document.
    • external_gte: Only index the document if the specified version is equal or higher than the version of the stored document or if there is no existing document. NOTE: The external_gte version type is meant for special use cases and should be used with care. If used incorrectly, it can result in loss of data.
    • force: This option is deprecated because it can cause primary and replica shards to diverge.

    Values are internal, external, external_gte, or force.

Delete a document Generally available

DELETE /{index}/_doc/{id}

Remove a JSON document from the specified index.

NOTE: You cannot send deletion requests directly to a data stream. To delete a document in a data stream, you must target the backing index containing the document.

Optimistic concurrency control

Delete operations can be made conditional and only be performed if the last modification to the document was assigned the sequence number and primary term specified by the if_seq_no and if_primary_term parameters. If a mismatch is detected, the operation will result in a VersionConflictException and a status code of 409.

Versioning

Each document indexed is versioned. When deleting a document, the version can be specified to make sure the relevant document you are trying to delete is actually being deleted and it has not changed in the meantime. Every write operation run on a document, deletes included, causes its version to be incremented. The version number of a deleted document remains available for a short time after deletion to allow for control of concurrent operations. The length of time for which a deleted document's version remains available is determined by the index.gc_deletes index setting.

Routing

If routing is used during indexing, the routing value also needs to be specified to delete a document.

If the _routing mapping is set to required and no routing value is specified, the delete API throws a RoutingMissingException and rejects the request.

For example:

DELETE /my-index-000001/_doc/1?routing=shard-1

This request deletes the document with ID 1, but it is routed based on the user. The document is not deleted if the correct routing is not specified.

Distributed

The delete operation gets hashed into a specific shard ID. It then gets redirected into the primary shard within that ID group and replicated (if needed) to shard replicas within that ID group.

Required authorization

  • Index privileges: delete

Path parameters

  • index string Required

    The name of the target index.

  • id string Required

    A unique identifier for the document.

Query parameters

  • if_primary_term number

    Only perform the operation if the document has this primary term.

  • if_seq_no number

    Only perform the operation if the document has this sequence number.

  • refresh string

    If true, Elasticsearch refreshes the affected shards to make this operation visible to search. If wait_for, it waits for a refresh to make this operation visible to search. If false, it does nothing with refreshes.

    Values are true, false, or wait_for.

  • routing string

    A custom value used to route operations to a specific shard.

  • timeout string

    The period to wait for active shards.

    This parameter is useful for situations where the primary shard assigned to perform the delete operation might not be available when the delete operation runs. Some reasons for this might be that the primary shard is currently recovering from a store or undergoing relocation. By default, the delete operation will wait on the primary shard to become available for up to 1 minute before failing and responding with an error.

    Values are -1 or 0.

  • version number

    An explicit version number for concurrency control. It must match the current version of the document for the request to succeed.

  • version_type string

    The version type.

    Supported values include:

    • internal: Use internal versioning that starts at 1 and increments with each update or delete.
    • external: Only index the document if the specified version is strictly higher than the version of the stored document or if there is no existing document.
    • external_gte: Only index the document if the specified version is equal or higher than the version of the stored document or if there is no existing document. NOTE: The external_gte version type is meant for special use cases and should be used with care. If used incorrectly, it can result in loss of data.
    • force: This option is deprecated because it can cause primary and replica shards to diverge.

    Values are internal, external, external_gte, or force.

  • wait_for_active_shards number | string

    The minimum number of shard copies that must be active before proceeding with the operation. You can set it to all or any positive integer up to the total number of shards in the index (number_of_replicas+1). The default value of 1 means it waits for each primary shard to be active.

    Values are all or index-setting.

Delete documents Generally available; Added in 5.0.0

POST /{index}/_delete_by_query

Deletes documents that match the specified query.

If the Elasticsearch security features are enabled, you must have the following index privileges for the target data stream, index, or alias:

  • read
  • delete or write

You can specify the query criteria in the request URI or the request body using the same syntax as the search API. When you submit a delete by query request, Elasticsearch gets a snapshot of the data stream or index when it begins processing the request and deletes matching documents using internal versioning. If a document changes between the time that the snapshot is taken and the delete operation is processed, it results in a version conflict and the delete operation fails.

NOTE: Documents with a version equal to 0 cannot be deleted using delete by query because internal versioning does not support 0 as a valid version number.

While processing a delete by query request, Elasticsearch performs multiple search requests sequentially to find all of the matching documents to delete. A bulk delete request is performed for each batch of matching documents. If a search or bulk request is rejected, the requests are retried up to 10 times, with exponential back off. If the maximum retry limit is reached, processing halts and all failed requests are returned in the response. Any delete requests that completed successfully still stick, they are not rolled back.

You can opt to count version conflicts instead of halting and returning by setting conflicts to proceed. Note that if you opt to count version conflicts the operation could attempt to delete more documents from the source than max_docs until it has successfully deleted max_docs documents, or it has gone through every document in the source query.

Throttling delete requests

To control the rate at which delete by query issues batches of delete operations, you can set requests_per_second to any positive decimal number. This pads each batch with a wait time to throttle the rate. Set requests_per_second to -1 to disable throttling.

Throttling uses a wait time between batches so that the internal scroll requests can be given a timeout that takes the request padding into account. The padding time is the difference between the batch size divided by the requests_per_second and the time spent writing. By default the batch size is 1000, so if requests_per_second is set to 500:

target_time = 1000 / 500 per second = 2 seconds
wait_time = target_time - write_time = 2 seconds - .5 seconds = 1.5 seconds

Since the batch is issued as a single _bulk request, large batch sizes cause Elasticsearch to create many requests and wait before starting the next set. This is "bursty" instead of "smooth".

Slicing

Delete by query supports sliced scroll to parallelize the delete process. This can improve efficiency and provide a convenient way to break the request down into smaller parts.

Setting slices to auto lets Elasticsearch choose the number of slices to use. This setting will use one slice per shard, up to a certain limit. If there are multiple source data streams or indices, it will choose the number of slices based on the index or backing index with the smallest number of shards. Adding slices to the delete by query operation creates sub-requests which means it has some quirks:

  • You can see these requests in the tasks APIs. These sub-requests are "child" tasks of the task for the request with slices.
  • Fetching the status of the task for the request with slices only contains the status of completed slices.
  • These sub-requests are individually addressable for things like cancellation and rethrottling.
  • Rethrottling the request with slices will rethrottle the unfinished sub-request proportionally.
  • Canceling the request with slices will cancel each sub-request.
  • Due to the nature of slices each sub-request won't get a perfectly even portion of the documents. All documents will be addressed, but some slices may be larger than others. Expect larger slices to have a more even distribution.
  • Parameters like requests_per_second and max_docs on a request with slices are distributed proportionally to each sub-request. Combine that with the earlier point about distribution being uneven and you should conclude that using max_docs with slices might not result in exactly max_docs documents being deleted.
  • Each sub-request gets a slightly different snapshot of the source data stream or index though these are all taken at approximately the same time.

If you're slicing manually or otherwise tuning automatic slicing, keep in mind that:

  • Query performance is most efficient when the number of slices is equal to the number of shards in the index or backing index. If that number is large (for example, 500), choose a lower number as too many slices hurts performance. Setting slices higher than the number of shards generally does not improve efficiency and adds overhead.
  • Delete performance scales linearly across available resources with the number of slices.

Whether query or delete performance dominates the runtime depends on the documents being reindexed and cluster resources.

Cancel a delete by query operation

Any delete by query can be canceled using the task cancel API. For example:

POST _tasks/r1A2WoRbTwKZ516z6NEs5A:36619/_cancel

The task ID can be found by using the get tasks API.

Cancellation should happen quickly but might take a few seconds. The get task status API will continue to list the delete by query task until this task checks that it has been cancelled and terminates itself.

Required authorization

  • Index privileges: read,delete

Path parameters

  • index string | array[string] Required

    A comma-separated list of data streams, indices, and aliases to search. It supports wildcards (*). To search all data streams or indices, omit this parameter or use * or _all.

Query parameters

  • allow_no_indices boolean

    If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices. For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.

  • analyzer string

    Analyzer to use for the query string. This parameter can be used only when the q query string parameter is specified.

  • analyze_wildcard boolean

    If true, wildcard and prefix queries are analyzed. This parameter can be used only when the q query string parameter is specified.

  • conflicts string

    What to do if delete by query hits version conflicts: abort or proceed.

    Supported values include:

    • abort: Stop reindexing if there are conflicts.
    • proceed: Continue reindexing even if there are conflicts.

    Values are abort or proceed.

  • default_operator string

    The default operator for query string query: AND or OR. This parameter can be used only when the q query string parameter is specified.

    Values are and, AND, or, or OR.

  • df string

    The field to use as default where no field prefix is given in the query string. This parameter can be used only when the q query string parameter is specified.

  • expand_wildcards string | array[string]

    The type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. It supports comma-separated values, such as open,hidden.

    Supported values include:

    • all: Match any data stream or index, including hidden ones.
    • open: Match open, non-hidden indices. Also matches any non-hidden data stream.
    • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
    • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
    • none: Wildcard expressions are not accepted.

    Values are all, open, closed, hidden, or none.

  • from number

    Skips the specified number of documents.

  • ignore_unavailable boolean

    If false, the request returns an error if it targets a missing or closed index.

  • lenient boolean

    If true, format-based query failures (such as providing text to a numeric field) in the query string will be ignored. This parameter can be used only when the q query string parameter is specified.

  • max_docs number

    The maximum number of documents to process. Defaults to all documents. When set to a value less then or equal to scroll_size, a scroll will not be used to retrieve the results for the operation.

  • preference string

    The node or shard the operation should be performed on. It is random by default.

  • refresh boolean

    If true, Elasticsearch refreshes all shards involved in the delete by query after the request completes. This is different than the delete API's refresh parameter, which causes just the shard that received the delete request to be refreshed. Unlike the delete API, it does not support wait_for.

  • request_cache boolean

    If true, the request cache is used for this request. Defaults to the index-level setting.

  • requests_per_second number

    The throttle for this request in sub-requests per second.

  • routing string

    A custom value used to route operations to a specific shard.

  • q string

    A query in the Lucene query string syntax.

  • scroll string

    The period to retain the search context for scrolling.

    Values are -1 or 0.

  • scroll_size number

    The size of the scroll request that powers the operation.

  • search_timeout string

    The explicit timeout for each search request. It defaults to no timeout.

    Values are -1 or 0.

  • search_type string

    The type of the search operation. Available options include query_then_fetch and dfs_query_then_fetch.

    Supported values include:

    • query_then_fetch: Documents are scored using local term and document frequencies for the shard. This is usually faster but less accurate.
    • dfs_query_then_fetch: Documents are scored using global term and document frequencies across all shards. This is usually slower but more accurate.

    Values are query_then_fetch or dfs_query_then_fetch.

  • slices number | string

    The number of slices this task should be divided into.

    Value is auto.

  • sort array[string]

    A comma-separated list of <field>:<direction> pairs.

  • stats array[string]

    The specific tag of the request for logging and statistical purposes.

  • terminate_after number

    The maximum number of documents to collect for each shard. If a query reaches this limit, Elasticsearch terminates the query early. Elasticsearch collects documents before sorting.

    Use with caution. Elasticsearch applies this parameter to each shard handling the request. When possible, let Elasticsearch perform early termination automatically. Avoid specifying this parameter for requests that target data streams with backing indices across multiple data tiers.

  • timeout string

    The period each deletion request waits for active shards.

    Values are -1 or 0.

  • version boolean

    If true, returns the document version as part of a hit.

  • wait_for_active_shards number | string

    The number of shard copies that must be active before proceeding with the operation. Set to all or any positive integer up to the total number of shards in the index (number_of_replicas+1). The timeout value controls how long each write request waits for unavailable shards to become available.

    Values are all or index-setting.

  • wait_for_completion boolean

    If true, the request blocks until the operation is complete. If false, Elasticsearch performs some preflight checks, launches the request, and returns a task you can use to cancel or get the status of the task. Elasticsearch creates a record of this task as a document at .tasks/task/${taskId}. When you are done with a task, you should delete the task document so Elasticsearch can reclaim the space.

Check for a document source Generally available; Added in 5.4.0

HEAD /{index}/_source/{id}

Check whether a document source exists in an index. For example:

Throttle a reindex operation Generally available; Added in 2.4.0

POST /_reindex/{task_id}/_rethrottle

Change the number of requests per second for a particular reindex operation. For example:

POST _reindex/r1A2WoRbTwKZ516z6NEs5A:36619/_rethrottle?requests_per_second=-1

Rethrottling that speeds up the query takes effect immediately. Rethrottling that slows down the query will take effect after completing the current batch. This behavior prevents scroll timeouts.

Path parameters

  • task_id string Required

    The task identifier, which can be found by using the tasks API.

Query parameters

  • requests_per_second number

    The throttle for this request in sub-requests per second. It can be either -1 to turn off throttling or any decimal number like 1.7 or 12 to throttle to that level.

Get term vector information Generally available

POST /{index}/_termvectors/{id}

All methods and paths for this operation:

GET /{index}/_termvectors

POST /{index}/_termvectors
GET /{index}/_termvectors/{id}
POST /{index}/_termvectors/{id}

Get information and statistics about terms in the fields of a particular document.

You can retrieve term vectors for documents stored in the index or for artificial documents passed in the body of the request. You can specify the fields you are interested in through the fields parameter or by adding the fields to the request body. For example:

GET /my-index-000001/_termvectors/1?fields=message

Fields can be specified using wildcards, similar to the multi match query.

Term vectors are real-time by default, not near real-time. This can be changed by setting realtime parameter to false.

You can request three types of values: term information, term statistics, and field statistics. By default, all term information and field statistics are returned for all fields but term statistics are excluded.

Term information

  • term frequency in the field (always returned)
  • term positions (positions: true)
  • start and end offsets (offsets: true)
  • term payloads (payloads: true), as base64 encoded bytes

If the requested information wasn't stored in the index, it will be computed on the fly if possible. Additionally, term vectors could be computed for documents not even existing in the index, but instead provided by the user.


Start and end offsets assume UTF-16 encoding is being used. If you want to use these offsets in order to get the original text that produced this token, you should make sure that the string you are taking a sub-string of is also encoded using UTF-16.

Behaviour

The term and field statistics are not accurate. Deleted documents are not taken into account. The information is only retrieved for the shard the requested document resides in. The term and field statistics are therefore only useful as relative measures whereas the absolute numbers have no meaning in this context. By default, when requesting term vectors of artificial documents, a shard to get the statistics from is randomly selected. Use routing only to hit a particular shard.

Required authorization

  • Index privileges: read

Path parameters

  • index string Required

    The name of the index that contains the document.

  • id string Required

    A unique identifier for the document.

Query parameters

  • fields string | array[string]

    A comma-separated list or wildcard expressions of fields to include in the statistics. It is used as the default list unless a specific field list is provided in the completion_fields or fielddata_fields parameters.

  • field_statistics boolean

    If true, the response includes:

    • The document count (how many documents contain this field).
    • The sum of document frequencies (the sum of document frequencies for all terms in this field).
    • The sum of total term frequencies (the sum of total term frequencies of each term in this field).
  • offsets boolean

    If true, the response includes term offsets.

  • payloads boolean

    If true, the response includes term payloads.

  • positions boolean

    If true, the response includes term positions.

  • preference string

    The node or shard the operation should be performed on. It is random by default.

  • realtime boolean

    If true, the request is real-time as opposed to near-real-time.

  • routing string

    A custom value that is used to route operations to a specific shard.

  • term_statistics boolean

    If true, the response includes:

    • The total term frequency (how often a term occurs in all documents).
    • The document frequency (the number of documents containing the current term).

    By default these values are not returned since term statistics can have a serious performance impact.

  • version number

    If true, returns the document version as part of a hit.

  • version_type string

    The version type.

    Supported values include:

    • internal: Use internal versioning that starts at 1 and increments with each update or delete.
    • external: Only index the document if the specified version is strictly higher than the version of the stored document or if there is no existing document.
    • external_gte: Only index the document if the specified version is equal or higher than the version of the stored document or if there is no existing document. NOTE: The external_gte version type is meant for special use cases and should be used with care. If used incorrectly, it can result in loss of data.
    • force: This option is deprecated because it can cause primary and replica shards to diverge.

    Values are internal, external, external_gte, or force.

application/json

Body

  • doc object

    An artificial document (a document not present in the index) for which you want to retrieve term vectors.

  • filter object

    Filter terms based on their tf-idf scores. This could be useful in order find out a good characteristic vector of a document. This feature works in a similar manner to the second phase of the More Like This Query.

Update a document Generally available

POST /{index}/_update/{id}

Update a document by running a script or passing a partial document.

If the Elasticsearch security features are enabled, you must have the index or write index privilege for the target index or index alias.

The script can update, delete, or skip modifying the document. The API also supports passing a partial document, which is merged into the existing document. To fully replace an existing document, use the index API. This operation:

  • Gets the document (collocated with the shard) from the index.
  • Runs the specified script.
  • Indexes the result.

The document must still be reindexed, but using this API removes some network roundtrips and reduces chances of version conflicts between the GET and the index operation.

The _source field must be enabled to use this API. In addition to _source, you can access the following variables through the ctx map: _index, _type, _id, _version, _routing, and _now (the current timestamp).

Required authorization

  • Index privileges: write

Path parameters

  • index string Required

    The name of the target index. By default, the index is created automatically if it doesn't exist.

  • id string Required

    A unique identifier for the document to be updated.

Query parameters

  • if_primary_term number

    Only perform the operation if the document has this primary term.

  • if_seq_no number

    Only perform the operation if the document has this sequence number.

  • include_source_on_error boolean

    True or false if to include the document source in the error message in case of parsing errors.

  • lang string

    The script language.

  • refresh string

    If 'true', Elasticsearch refreshes the affected shards to make this operation visible to search. If 'wait_for', it waits for a refresh to make this operation visible to search. If 'false', it does nothing with refreshes.

    Values are true, false, or wait_for.

  • require_alias boolean

    If true, the destination must be an index alias.

  • retry_on_conflict number

    The number of times the operation should be retried when a conflict occurs.

  • routing string

    A custom value used to route operations to a specific shard.

  • timeout string

    The period to wait for the following operations: dynamic mapping updates and waiting for active shards. Elasticsearch waits for at least the timeout period before failing. The actual wait time could be longer, particularly when multiple waits occur.

    Values are -1 or 0.

  • wait_for_active_shards number | string

    The number of copies of each shard that must be active before proceeding with the operation. Set to 'all' or any positive integer up to the total number of shards in the index (number_of_replicas+1). The default value of 1 means it waits for each primary shard to be active.

    Values are all or index-setting.

  • _source boolean | string | array[string]

    If false, source retrieval is turned off. You can also specify a comma-separated list of the fields you want to retrieve.

  • _source_excludes string | array[string]

    The source fields you want to exclude.

  • _source_includes string | array[string]

    The source fields you want to retrieve.

application/json

Body Required

  • detect_noop boolean

    If true, the result in the response is set to noop (no operation) when there are no changes to the document.

    Default value is true.

  • doc object

    A partial update to an existing document. If both doc and script are specified, doc is ignored.

  • doc_as_upsert boolean

    If true, use the contents of 'doc' as the value of 'upsert'. NOTE: Using ingest pipelines with doc_as_upsert is not supported.

    Default value is false.

  • script object

    The script to run to update the document.

    Hide script attributes Show script attributes object
    • source string

      The script source.

    • id string

      The id for a stored script.

    • params object

      Specifies any named parameters that are passed into the script as variables. Use parameters instead of hard-coded values to decrease compile time.

      Hide params attribute Show params attribute object
      • * object Additional properties
    • lang string

      Specifies the language the script is written in.

      Supported values include:

}
Run `POST test/_update/1` to perform a scripted upsert. When `scripted_upsert` is `true`, the script runs whether or not the document exists.
{
  "scripted_upsert": true,
  "script": {
    "source": """
      if ( ctx.op == 'create' ) {
        ctx._source.counter = params.count

      }
    """,
    "params": {
      "count": 4
    }
  },
  "upsert": {}
}
Run `POST test/_update/1` to perform a doc as upsert. Instead of sending a partial `doc` plus an `upsert` doc, you can set `doc_as_upsert` to `true` to use the contents of `doc` as the `upsert` value.
{
  "doc": {
    "name": "new_name"
  },
  "doc_as_upsert": true
}
Run `POST test/_update/1` to use a script to add a tag to a list of tags. In this example, it is just a list, so the tag is added even it exists.
{
  "script": {
    "source": "ctx._source.tags.add(params.tag)",
    "lang": "painless",
    "params": {
      "tag": "blue"
    }
  }
}
Run `POST test/_update/1` to use a script to remove a tag from a list of tags. The Painless function to remove a tag takes the array index of the element you want to remove. To avoid a possible runtime error, you first need to make sure the tag exists. If the list contains duplicates of the tag, this script just removes one occurrence.
{
  "script": {
    "source": "if (ctx._source.tags.contains(params.tag)) { ctx._source.tags.remove(ctx._source.tags.indexOf(params.tag)) }",
    "lang": "painless",
    "params": {
      "tag": "blue"
    }
  }
}
Run `POST test/_update/1` to use a script to add a field `new_field` to the document.
{
  "script" : "ctx._source.new_field = 'value_of_new_field'"
}
Run `POST test/_update/1` to use a script to remove a field `new_field` from the document.
{
  "script" : "ctx._source.remove('new_field')"
}
Run `POST test/_update/1` to use a script to remove a subfield from an object field.
{
  "script": "ctx._source['my-object'].remove('my-subfield')"
}
Run `POST test/_update/1` to change the operation that runs from within the script. For example, this request deletes the document if the `tags` field contains `green`, otherwise it does nothing (`noop`).
{
  "script": {
    "source": "if (ctx._source.tags.contains(params.tag)) { ctx.op = 'delete' } else { ctx.op = 'noop' }",
    "lang": "painless",

Run `POST test/_update/1` to do a partial update that adds a new field to the existing document.
{
  "doc": {
    "name": "new_name"
  }
}
Run `POST test/_update/1` to perfom an upsert. If the document does not already exist, the contents of the upsert element are inserted as a new document. If the document exists, the script is run.

Update documents Generally available; Added in 2.4.0

POST /{index}/_update_by_query

Updates documents that match the specified query. If no query is specified, performs an update on every document in the data stream or index without modifying the source, which is useful for picking up mapping changes.

If the Elasticsearch security features are enabled, you must have the following index privileges for the target data stream, index, or alias:

  • read
  • index or write

You can specify the query criteria in the request URI or the request body using the same syntax as the search API.

When you submit an update by query request, Elasticsearch gets a snapshot of the data stream or index when it begins processing the request and updates matching documents using internal versioning. When the versions match, the document is updated and the version number is incremented. If a document changes between the time that the snapshot is taken and the update operation is processed, it results in a version conflict and the operation fails. You can opt to count version conflicts instead of halting and returning by setting conflicts to proceed. Note that if you opt to count version conflicts, the operation could attempt to update more documents from the source than max_docs until it has successfully updated max_docs documents or it has gone through every document in the source query.

NOTE: Documents with a version equal to 0 cannot be updated using update by query because internal versioning does not support 0 as a valid version number.

While processing an update by query request, Elasticsearch performs multiple search requests sequentially to find all of the matching documents. A bulk update request is performed for each batch of matching documents. Any query or update failures cause the update by query request to fail and the failures are shown in the response. Any update requests that completed successfully still stick, they are not rolled back.

Throttling update requests

To control the rate at which update by query issues batches of update operations, you can set requests_per_second to any positive decimal number. This pads each batch with a wait time to throttle the rate. Set requests_per_second to -1 to turn off throttling.

Throttling uses a wait time between batches so that the internal scroll requests can be given a timeout that takes the request padding into account. The padding time is the difference between the batch size divided by the requests_per_second and the time spent writing. By default the batch size is 1000, so if requests_per_second is set to 500:

target_time = 1000 / 500 per second = 2 seconds
wait_time = target_time - write_time = 2 seconds - .5 seconds = 1.5 seconds

Since the batch is issued as a single _bulk request, large batch sizes cause Elasticsearch to create many requests and wait before starting the next set. This is "bursty" instead of "smooth".

Slicing

Update by query supports sliced scroll to parallelize the update process. This can improve efficiency and provide a convenient way to break the request down into smaller parts.

Setting slices to auto chooses a reasonable number for most data streams and indices. This setting will use one slice per shard, up to a certain limit. If there are multiple source data streams or indices, it will choose the number of slices based on the index or backing index with the smallest number of shards.

Adding slices to _update_by_query just automates the manual process of creating sub-requests, which means it has some quirks:

  • You can see these requests in the tasks APIs. These sub-requests are "child" tasks of the task for the request with slices.
  • Fetching the status of the task for the request with slices only contains the status of completed slices.
  • These sub-requests are individually addressable for things like cancellation and rethrottling.
  • Rethrottling the request with slices will rethrottle the unfinished sub-request proportionally.
  • Canceling the request with slices will cancel each sub-request.
  • Due to the nature of slices each sub-request won't get a perfectly even portion of the documents. All documents will be addressed, but some slices may be larger than others. Expect larger slices to have a more even distribution.
  • Parameters like requests_per_second and max_docs on a request with slices are distributed proportionally to each sub-request. Combine that with the point above about distribution being uneven and you should conclude that using max_docs with slices might not result in exactly max_docs documents being updated.
  • Each sub-request gets a slightly different snapshot of the source data stream or index though these are all taken at approximately the same time.

If you're slicing manually or otherwise tuning automatic slicing, keep in mind that:

  • Query performance is most efficient when the number of slices is equal to the number of shards in the index or backing index. If that number is large (for example, 500), choose a lower number as too many slices hurts performance. Setting slices higher than the number of shards generally does not improve efficiency and adds overhead.
  • Update performance scales linearly across available resources with the number of slices.

Whether query or update performance dominates the runtime depends on the documents being reindexed and cluster resources.

Update the document source

Update by query supports scripts to update the document source. As with the update API, you can set ctx.op to change the operation that is performed.

Set ctx.op = "noop" if your script decides that it doesn't have to make any changes. The update by query operation skips updating the document and increments the noop counter.

Set ctx.op = "delete" if your script decides that the document should be deleted. The update by query operation deletes the document and increments the deleted counter.

Update by query supports only index, noop, and delete. Setting ctx.op to anything else is an error. Setting any other field in ctx is an error. This API enables you to only modify the source of matching documents; you cannot move them.

Required authorization

  • Index privileges: read,write

Path parameters

  • index string | array[string] Required

    A comma-separated list of data streams, indices, and aliases to search. It supports wildcards (*). To search all data streams or indices, omit this parameter or use * or _all.

Query parameters

  • allow_no_indices boolean

    If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices. For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.

  • analyzer string

    The analyzer to use for the query string. This parameter can be used only when the q query string parameter is specified.

  • analyze_wildcard boolean

    If true, wildcard and prefix queries are analyzed. This parameter can be used only when the q query string parameter is specified.

  • conflicts string

    The preferred behavior when update by query hits version conflicts: abort or proceed.

    Supported values include:

    • abort: Stop reindexing if there are conflicts.
    • proceed: Continue reindexing even if there are conflicts.

    Values are abort or proceed.

  • default_operator string

    The default operator for query string query: AND or OR. This parameter can be used only when the q query string parameter is specified.

    Values are and, AND, or, or OR.

  • df string

    The field to use as default where no field prefix is given in the query string. This parameter can be used only when the q query string parameter is specified.

  • expand_wildcards string | array[string]

    The type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. It supports comma-separated values, such as open,hidden.

    Supported values include:

    • all: Match any data stream or index, including hidden ones.
    • open: Match open, non-hidden indices. Also matches any non-hidden data stream.
    • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
    • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
    • none: Wildcard expressions are not accepted.

    Values are all, open, closed, hidden, or none.

  • from number

    Skips the specified number of documents.

  • ignore_unavailable boolean

    If false, the request returns an error if it targets a missing or closed index.

  • lenient boolean

    If true, format-based query failures (such as providing text to a numeric field) in the query string will be ignored. This parameter can be used only when the q query string parameter is specified.

  • max_docs number

    The maximum number of documents to process. It defaults to all documents. When set to a value less then or equal to scroll_size then a scroll will not be used to retrieve the results for the operation.

  • pipeline string

    The ID of the pipeline to use to preprocess incoming documents. If the index has a default ingest pipeline specified, then setting the value to _none disables the default ingest pipeline for this request. If a final pipeline is configured it will always run, regardless of the value of this parameter.

  • preference string

    The node or shard the operation should be performed on. It is random by default.

  • q string

    A query in the Lucene query string syntax.

  • refresh boolean

    If true, Elasticsearch refreshes affected shards to make the operation visible to search after the request completes. This is different than the update API's refresh parameter, which causes just the shard that received the request to be refreshed.

  • request_cache boolean

    If true, the request cache is used for this request. It defaults to the index-level setting.

  • requests_per_second number

    The throttle for this request in sub-requests per second.

  • routing string

    A custom value used to route operations to a specific shard.

  • scroll string

    The period to retain the search context for scrolling.

    Values are -1 or 0.

  • scroll_size number

    The size of the scroll request that powers the operation.

  • search_timeout string

    An explicit timeout for each search request. By default, there is no timeout.

    Values are -1 or 0.

  • search_type string

    The type of the search operation. Available options include query_then_fetch and dfs_query_then_fetch.

    Supported values include:

    • query_then_fetch: Documents are scored using local term and document frequencies for the shard. This is usually faster but less accurate.
    • dfs_query_then_fetch: Documents are scored using global term and document frequencies across all shards. This is usually slower but more accurate.

    Values are query_then_fetch or dfs_query_then_fetch.

  • slices number | string

    The number of slices this task should be divided into.

    Value is auto.

  • sort array[string]

    A comma-separated list of : pairs.

  • stats array[string]

    The specific tag of the request for logging and statistical purposes.

  • terminate_after number

    The maximum number of documents to collect for each shard. If a query reaches this limit, Elasticsearch terminates the query early. Elasticsearch collects documents before sorting.

    IMPORTANT: Use with caution. Elasticsearch applies this parameter to each shard handling the request. When possible, let Elasticsearch perform early termination automatically. Avoid specifying this parameter for requests that target data streams with backing indices across multiple data tiers.

  • timeout string

    The period each update request waits for the following operations: dynamic mapping updates, waiting for active shards. By default, it is one minute. This guarantees Elasticsearch waits for at least the timeout before failing. The actual wait time could be longer, particularly when multiple waits occur.

    Values are -1 or 0.

  • version boolean

    If true, returns the document version as part of a hit.

  • version_type boolean

    Should the document increment the version number (internal) on hit or not (reindex)

  • wait_for_active_shards number | string

    The number of shard copies that must be active before proceeding with the operation. Set to all or any positive integer up to the total number of shards in the index (number_of_replicas+1). The timeout parameter controls how long each write request waits for unavailable shards to become available. Both work exactly the way they work in the bulk API.

    Values are all or index-setting.

  • wait_for_completion boolean

    If true, the request blocks until the operation is complete. If false, Elasticsearch performs some preflight checks, launches the request, and returns a task ID that you can use to cancel or get the status of the task. Elasticsearch creates a record of this task as a document at .tasks/task/${taskId}.

ES|QL

The Elasticsearch Query Language (ES|QL) provides a powerful way to filter, transform, and analyze data stored in Elasticsearch, and in the future in other runtimes.

Learn more about ES|QL

Run an async ES|QL query Generally available; Added in 8.13.0

POST /_query/async

Asynchronously run an ES|QL (Elasticsearch query language) query, monitor its progress, and retrieve results when they become available.

The API accepts the same parameters and request body as the synchronous query API, along with additional async related properties.

Required authorization

  • Index privileges: read
External documentation

Query parameters

  • allow_partial_results boolean

    If true, partial results will be returned if there are shard failures, but the query can continue to execute on other clusters and shards. If false, the query will fail if there are any failures.

    To override the default behavior, you can set the esql.query.allow_partial_results cluster setting to false.

  • delimiter string

    The character to use between values within a CSV row. It is valid only for the CSV format.

  • drop_null_columns boolean

    Indicates whether columns that are entirely null will be removed from the columns and values portion of the results. If true, the response will include an extra section under the name all_columns which has the name of all the columns.

  • format string

    A short version of the Accept header, e.g. json, yaml.

    csv, tsv, and txt formats will return results in a tabular format, excluding other metadata fields from the response.

    For async requests, nothing will be returned if the async query doesn't finish within the timeout. The query ID and running status are available in the X-Elasticsearch-Async-Id and X-Elasticsearch-Async-Is-Running HTTP headers of the response, respectively.

    Values are csv, json, tsv, txt, yaml, cbor, smile, or arrow.

application/json

Body Required

  • columnar boolean

    By default, ES|QL returns results as rows. For example, FROM returns each individual document as one row. For the JSON, YAML, CBOR and smile formats, ES|QL can return the results in a columnar fashion where one row represents all the values of a certain column in the results.

  • filter object

    Specify a Query DSL query in the filter parameter to filter the set of documents that an ES|QL query runs on.

    External documentation
  • locale string
  • params array[number | string | boolean | null | object]

    To avoid any attempts of hacking or code injection, extract the values in a separate list of parameters. Use question mark placeholders (?) in the query string for each of the parameters.

    A field value.

  • profile boolean

    If provided and true the response will include an extra profile object with information on how the query was executed. This information is for human debugging and its format can change at any time but it can give some insight into the performance of each part of the query.

  • query string Required

    The ES|QL query API accepts an ES|QL query string in the query parameter, runs it, and returns the results.

  • tables object

    Tables to use with the LOOKUP operation. The top level key is the table name and the next level key is the column name.

    Hide tables attribute Show tables attribute object
  • include_ccs_metadata boolean

    When set to true and performing a cross-cluster query, the response will include an extra _clusters object with information about the clusters that participated in the search along with info such as shards count.

    Default value is false.

  • wait_for_completion_timeout string

    The period to wait for the request to finish. By default, the request waits for 1 second for the query results. If the query completes during this period, results are returned Otherwise, a query ID is returned that can later be used to retrieve the results.

  • keep_alive string

    The period for which the query and its results are stored in the cluster. The default period is five days. When this period expires, the query and its results are deleted, even if the query is still ongoing. If the keep_on_completion parameter is false, Elasticsearch only stores async queries that do not complete within the period set by the wait_for_completion_timeout parameter, regardless of this value.

  • keep_on_completion boolean

    Indicates whether the query and its results are stored in the cluster. If false, the query and its results are stored in the cluster only if the request does not complete during the period set by the wait_for_completion_timeout parameter.

    Default value is false.

Features

The feature APIs enable you to introspect and manage features provided by Elasticsearch and Elasticsearch plugins.

Get the features Generally available; Added in 7.12.0

GET /_features

Get a list of features that can be included in snapshots using the feature_states field when creating a snapshot. You can use this API to determine which feature states to include when taking a snapshot. By default, all feature states are included in a snapshot if that snapshot includes the global state, or none if it does not.

A feature state includes one or more system indices necessary for a given feature to function. In order to ensure data integrity, all system indices that comprise a feature state are snapshotted and restored together.

The features listed by this API are a combination of built-in features and features defined by plugins. In order for a feature state to be listed in this API and recognized as a valid feature state by the create snapshot API, the plugin that defines that feature must be installed on the master node.

      • sentence: Break highlighted fragments at the next sentence boundary, as determined by Java’s BreakIterator. You can specify the locale to use with boundary_scanner_locale. When used with the unified highlighter, the sentence scanner splits sentences bigger than fragment_size at the first word boundary next to fragment_size. You can set fragment_size to 0 to never split any sentence.

      External documentation
    • max_fragment_length number
    • max_analyzed_offset number

      If set to a non-negative value, highlighting stops at this defined maximum limit. The rest of the text is not processed, thus not highlighted and no error is returned The max_analyzed_offset query setting does not override the index.highlight.max_analyzed_offset setting, which prevails when it’s set to lower value than the query setting.

    • phrase_limit number

      Controls the number of matching phrases in a document that are considered. Prevents the fvh highlighter from analyzing too many phrases and consuming too much memory. When using matched_fields, phrase_limit phrases per matched field are considered. Raising the limit increases query time and consumes more memory. Only supported by the fvh highlighter.

      Default value is 256.

Graph explore

The graph explore API enables you to extract and summarize information about the documents and terms in an Elasticsearch data stream or index.

Get started with Graph

Explore graph analytics Generally available

POST /{index}/_graph/explore

All methods and paths for this operation:

GET /{index}/_graph/explore

POST /{index}/_graph/explore

Extract and summarize information about the documents and terms in an Elasticsearch data stream or index. The easiest way to understand the behavior of this API is to use the Graph UI to explore connections. An initial request to the _explore API contains a seed query that identifies the documents of interest and specifies the fields that define the vertices and connections you want to include in the graph. Subsequent requests enable you to spider out from one more vertices of interest. You can exclude vertices that have already been returned.

External documentation

Path parameters

  • index string | array[string] Required

    Name of the index.

Query parameters

  • routing string

    Custom value used to route operations to a specific shard.

  • timeout string

    Specifies the period of time to wait for a response from each shard. If no response is received before the timeout expires, the request fails and returns an error. Defaults to no timeout.

    Values are -1 or 0.

application/json

Body

  • connections object

    Specifies or more fields from which you want to extract terms that are associated with the specified vertices.

    Hide connections attributes Show connections attributes object
    • connections object

      Specifies one or more fields from which you want to extract terms that are associated with the specified vertices.

    • query object Required

      An optional guiding query that constrains the Graph API as it explores connected terms.

      External documentation
    • vertices array[object] Required

      Contains the fields you are interested in.

      Hide vertices attributes Show vertices attributes object
      • exclude array[string]

        Prevents the specified terms from being included in the results.

      • field string Required

        Identifies a field in the documents of interest.

      • include array[object]

        Identifies the terms of interest that form the starting points from which you want to spider out.

        Hide include attributes Show include attributes object
        • boost number Required
        • term string Required
      • min_doc_count number

        Specifies how many documents must contain a pair of terms before it is considered to be a useful connection. This setting acts as a certainty threshold.

        Default value is 3.

      • shard_min_doc_count number

        Controls how many documents on a particular shard have to contain a pair of terms before the connection is returned for global consideration.

        Default value is 2.

      • size number

        Specifies the maximum number of vertex terms returned for each field.

        Default value is 5.

  • controls object

    Direct the Graph API how to build the graph.

    Hide controls attributes Show controls attributes object
    • sample_diversity object

      To avoid the top-matching documents sample being dominated by a single source of results, it is sometimes necessary to request diversity in the sample. You can do this by selecting a single-value field and setting a maximum number of documents per value for that field.

      Hide sample_diversity attributes Show sample_diversity attributes object
      • field string Required

        Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.

      • max_docs_per_value number Required
    • sample_size number

      Each hop considers a sample of the best-matching documents on each shard. Using samples improves the speed of execution and keeps exploration focused on meaningfully-connected terms. Very small values (less than 50) might not provide sufficient weight-of-evidence to identify significant connections between terms. Very large sample sizes can dilute the quality of the results and increase execution times.

      Default value is 100.

    • timeout string

      The length of time in milliseconds after which exploration will be halted and the results gathered so far are returned. This timeout is honored on a best-effort basis. Execution might overrun this timeout if, for example, a long pause is encountered while FieldData is loaded for a field.

    • use_significance boolean Required

      Filters associated terms so only those that are significantly associated with your query are included.

  • query object

    A seed query that identifies the documents of interest. Can be any valid Elasticsearch query.

    External documentation
  • vertices array[object]

    Specifies one or more fields that contain the terms you want to include in the graph as vertices.

    Hide vertices attributes Show vertices attributes object
    • exclude array[string]

      Default value is 2.

    • size number

      Specifies the maximum number of vertex terms returned for each field.

      Default value is 5.

Request example
Run `POST clicklogs/_graph/explore` for a basic exploration An initial graph explore query typically begins with a query to identify strongly related terms. Seed the exploration with a query. This example is searching `clicklogs` for people who searched for the term `midi`.Identify the vertices to include in the graph. This example is looking for product codes that are significantly associated with searches for `midi`. Find the connections. This example is looking for other search terms that led people to click on the products that are associated with searches for `midi`.

Import a dangling index Generally available; Added in 7.9.0

POST /_dangling/{index_uuid}

If Elasticsearch encounters index data that is absent from the current cluster state, those indices are considered to be dangling. For example, this can happen if you delete more than cluster.indices.tombstones.size indices while an Elasticsearch node is offline.

Path parameters

  • index_uuid string Required

    The UUID of the index to import. Use the get dangling indices API to locate the UUID.

Query parameters

  • accept_data_loss boolean Required

    This parameter must be set to true to import a dangling index. Because Elasticsearch cannot know where the dangling index data came from or determine which shard copies are fresh and which are stale, it cannot guarantee that the imported data represents the latest state of the index when it was last in the cluster.

  • master_timeout string

    Specify timeout for connection to master

    Values are -1 or 0.

  • timeout string

    Explicit operation timeout

    Values are -1 or 0.

Required authorization

  • Cluster privileges: manage

Path parameters

  • index_uuid string Required

    The UUID of the index to delete. Use the get dangling indices API to find the UUID.

Query parameters

  • accept_data_loss boolean Required

    This parameter must be set to true to acknowledge that it will no longer be possible to recove data from the dangling index.

  • master_timeout string

    Specify timeout for connection to master

    Values are -1 or 0.

    Comma-separated list of data streams, indices, and aliases used to limit the request. Supports wildcards (*). To target all data streams and indices, omit this parameter or use * or _all.

  • allow_no_indices boolean

    If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices.

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden.

    Supported values include:

    • all: Match any data stream or index, including hidden ones.
    • open: Match open, non-hidden indices. Also matches any non-hidden data stream.
    • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
    • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
    • none: Wildcard expressions are not accepted.

    Values are all, open, closed, hidden, or none.

  • fielddata boolean

    If true, clears the fields cache. Use the fields parameter to clear the cache of specific fields only.

  • fields string | array[string]

    Comma-separated list of field names used to limit the fielddata parameter.

  • ignore_unavailable boolean

    If false, the request returns an error if it targets a missing or closed index.

  • query boolean

    If true, clears the query cache.

Create or update a legacy index template Deprecated Generally available

POST /_template/{name}

All methods and paths for this operation:

PUT /_template/{name}

POST /_template/{name}

Index templates define settings, mappings, and aliases that can be applied automatically to new indices. Elasticsearch applies templates to new indices based on an index pattern that matches the index name.

IMPORTANT: This documentation is about legacy index templates, which are deprecated and will be replaced by the composable templates introduced in Elasticsearch 7.8.

Composable templates always take precedence over legacy templates. If no composable template matches a new index, matching legacy templates are applied according to their order.

Index templates are only applied during index creation. Changes to index templates do not affect existing indices. Settings and mappings specified in create index API requests override any settings or mappings specified in an index template.

You can use C-style /* *\/ block comments in index templates. You can include comments anywhere in the request body, except before the opening curly bracket.

Indices matching multiple templates

Multiple index templates can potentially match an index, in this case, both the settings and mappings are merged into the final configuration of the index. The order of the merging can be controlled using the order parameter, with lower order being applied first, and higher orders overriding them. NOTE: Multiple matching templates with the same order value will result in a non-deterministic merging order.

Required authorization

  • Cluster privileges: manage_index_templates,manage

Analyze the index disk usage Technical preview; Added in 7.15.0

POST /{index}/_disk_usage

Analyze the disk usage of each field of an index or data stream. This API might not support indices created in previous Elasticsearch versions. The result of a small index can be inaccurate as some parts of an index might not be analyzed by the API.

NOTE: The total size of fields of the analyzed shards of the index in the response is usually smaller than the index store_size value because some small metadata files are ignored and some parts of data files might not be scanned by the API. Since stored fields are stored together in a compressed format, the sizes of stored fields are also estimates and can be inaccurate. The stored size of the _id field is likely underestimated while the _source field is overestimated.

Path parameters

  • index string | array[string] Required

    Comma-separated list of data streams, indices, and aliases used to limit the request. It’s recommended to execute this API with a single index (or the latest backing index of a data stream) as the API consumes resources significantly.

Query parameters

  • allow_no_indices boolean

    If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices. For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden.

    Supported values include:

    • all: Match any data stream or index, including hidden ones.
    • open: Match open, non-hidden indices. Also matches any non-hidden data stream.
    • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
    • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
    • none: Wildcard expressions are not accepted.

    Values are all, open, closed, hidden, or none.

  • flush boolean

    If true, the API performs a flush before analysis. If false, the response may not include uncommitted data.

  • ignore_unavailable boolean

    If true, missing or closed indices are not included in the response.

  • run_expensive_tasks boolean

    Analyzing field disk usage is resource-intensive. To use the API, this parameter must be set to true.

Force a merge Generally available; Added in 2.1.0

POST /{index}/_forcemerge

All methods and paths for this operation:

POST /_forcemerge

POST /{index}/_forcemerge

Perform the force merge operation on the shards of one or more indices. For data streams, the API forces a merge on the shards of the stream's backing indices.

Merging reduces the number of segments in each shard by merging some of them together and also frees up the space used by deleted documents. Merging normally happens automatically, but sometimes it is useful to trigger a merge manually.

WARNING: We recommend force merging only a read-only index (meaning the index is no longer receiving writes). When documents are updated or deleted, the old version is not immediately removed but instead soft-deleted and marked with a "tombstone". These soft-deleted documents are automatically cleaned up during regular segment merges. But force merge can cause very large (greater than 5 GB) segments to be produced, which are not eligible for regular merges. So the number of soft-deleted documents can then grow rapidly, resulting in higher disk usage and worse search performance. If you regularly force merge an index receiving writes, this can also make snapshots more expensive, since the new documents can't be backed up incrementally.

Blocks during a force merge

Calls to this API block until the merge is complete (unless request contains wait_for_completion=false). If the client connection is lost before completion then the force merge process will continue in the background. Any new requests to force merge the same indices will also block until the ongoing force merge is complete.

Running force merge asynchronously

If the request contains wait_for_completion=false, Elasticsearch performs some preflight checks, launches the request, and returns a task you can use to get the status of the task. However, you can not cancel this task as the force merge task is not cancelable. Elasticsearch creates a record of this task as a document at _tasks/<task_id>. When you are done with a task, you should delete the task document so Elasticsearch can reclaim the space.

Force merging multiple indices

You can force merge multiple indices with a single request by targeting:

  • One or more data streams that contain multiple backing indices
  • Multiple indices
  • One or more aliases
  • All data streams and indices in a cluster

Each targeted shard is force-merged separately using the force_merge threadpool. By default each node only has a single force_merge thread which means that the shards on that node are force-merged one at a time. If you expand the force_merge threadpool on a node then it will force merge its shards in parallel

Force merge makes the storage for the shard being merged temporarily increase, as it may require free space up to triple its size in case max_num_segments parameter is set to 1, to rewrite all segments into a new one.

Data streams and time-based indices

Force-merging is useful for managing a data stream's older backing indices and other time-based indices, particularly after a rollover. In these cases, each index only receives indexing traffic for a certain period of time. Once an index receive no more writes, its shards can be force-merged to a single segment. This can be a good idea because single-segment shards can sometimes use simpler and more efficient data structures to perform searches. For example:

POST /.ds-my-data-stream-2099.03.07-000001/_forcemerge?max_num_segments=1

Update field mappings Generally available

POST /{index}/_mapping

All methods and paths for this operation:

PUT /{index}/_mapping

POST /{index}/_mapping

Add new fields to an existing data stream or index. You can also use this API to change the search settings of existing fields and add new properties to existing object fields. For data streams, these changes are applied to all backing indices by default.

Add multi-fields to an existing field

Multi-fields let you index the same field in different ways. You can use this API to update the fields mapping parameter and enable multi-fields for an existing field. WARNING: If an index (or data stream) contains documents when you add a multi-field, those documents will not have values for the new multi-field. You can populate the new multi-field with the update by query API.

Change supported mapping parameters for an existing field

The documentation for each mapping parameter indicates whether you can update it for an existing field using this API. For example, you can use the update mapping API to update the ignore_above parameter.

Change the mapping of an existing field

Except for supported mapping parameters, you can't change the mapping or field type of an existing field. Changing an existing field could invalidate data that's already indexed.

If you need to change the mapping of a field in a data stream's backing indices, refer to documentation about modifying data streams. If you need to change the mapping of a field in other indices, create a new index with the correct mapping and reindex your data into that index.

Rename a field

Renaming a field would invalidate data already indexed under the old field name. Instead, add an alias field to create an alternate field name.

Update index settings Generally available

PUT /{index}/_settings

All methods and paths for this operation:

PUT /_settings

PUT /{index}/_settings

Changes dynamic index settings in real time. For data streams, index setting changes are applied to all backing indices by default.

To revert a setting to the default value, use a null value. The list of per-index settings that can be updated dynamically on live indices can be found in index settings documentation. To preserve existing settings from being updated, set the preserve_existing parameter to true.

There are multiple valid ways to represent index settings in the request body. You can specify only the setting, for example:

{
  "number_of_replicas": 1
}

Or you can use an index setting object:

{
  "index": {
    "number_of_replicas": 1
  }
}

Or you can use dot annotation:

{
  "index.number_of_replicas": 1
}

Or you can embed any of the aforementioned options in a settings object. For example:

{
  "settings": {
    "index": {
      "number_of_replicas": 1
    }
  }
}

NOTE: You can only define new analyzers on closed indices. To add an analyzer, you must close the index, define the analyzer, and reopen the index. You cannot close the write index of a data stream. To update the analyzer for a data stream's write index and future backing indices, update the analyzer in the index template used by the stream. Then roll over the data stream to apply the new analyzer to the stream's write index and future backing indices. This affects searches and any new data added to the stream after the rollover. However, it does not affect the data stream's backing indices or their existing data. To change the analyzer for existing backing indices, you must create a new data stream and reindex your data into it.

Roll over to a new index Generally available; Added in 5.0.0

POST /{alias}/_rollover/{new_index}

All methods and paths for this operation:

POST /{alias}/_rollover

POST /{alias}/_rollover/{new_index}

TIP: We recommend using the index lifecycle rollover action to automate rollovers. However, Serverless does not support Index Lifecycle Management (ILM), so don't use this approach in the Serverless context.

The rollover API creates a new index for a data stream or index alias. The API behavior depends on the rollover target.

Roll over a data stream

If you roll over a data stream, the API creates a new write index for the stream. The stream's previous write index becomes a regular backing index. A rollover also increments the data stream's generation.

Roll over an index alias with a write index

TIP: Prior to Elasticsearch 7.9, you'd typically use an index alias with a write index to manage time series data. Data streams replace this functionality, require less maintenance, and automatically integrate with data tiers.

If an index alias points to multiple indices, one of the indices must be a write index. The rollover API creates a new write index for the alias with is_write_index set to true. The API also sets is_write_index to false for the previous write index.

Roll over an index alias with one index

If you roll over an index alias that points to only one index, the API creates a new index for the alias and removes the original index from the alias.

NOTE: A rollover creates a new index and is subject to the wait_for_active_shards setting.

Increment index names for an alias

When you roll over an index alias, you can specify a name for the new index. If you don't specify a name and the current index ends with - and a number, such as my-index-000001 or my-index-3, the new index name increments that number. For example, if you roll over an alias with a current index of my-index-000001, the rollover creates a new index named my-index-000002. This number is always six characters and zero-padded, regardless of the previous index's name.

If you use an index alias for time series data, you can use date math in the index name to track the rollover date. For example, you can create an alias that points to an index named <my-index-{now/d}-000001>. If you create the index on May 6, 2099, the index's name is my-index-2099.05.06-000001. If you roll over the alias on May 7, 2099, the new index's name is my-index-2099.05.07-000002.

    • open: Match open, non-hidden indices. Also matches any non-hidden data stream.
    • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
    • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
    • none: Wildcard expressions are not accepted.

    Values are all, open, closed, hidden, or none.

Shrink an index Generally available; Added in 5.0.0

POST /{index}/_shrink/{target}

All methods and paths for this operation:

PUT /{index}/_shrink/{target}

POST /{index}/_shrink/{target}

Shrink an index into a new index with fewer primary shards.

Before you can shrink an index:

  • The index must be read-only.
  • A copy of every shard in the index must reside on the same node.
  • The index must have a green health status.

To make shard allocation easier, we recommend you also remove the index's replica shards. You can later re-add replica shards as part of the shrink operation.

The requested number of primary shards in the target index must be a factor of the number of shards in the source index. For example an index with 8 primary shards can be shrunk into 4, 2 or 1 primary shards or an index with 15 primary shards can be shrunk into 5, 3 or 1. If the number of shards in the index is a prime number it can only be shrunk into a single primary shard Before shrinking, a (primary or replica) copy of every shard in the index must be present on the same node.

The current write index on a data stream cannot be shrunk. In order to shrink the current write index, the data stream must first be rolled over so that a new write index is created and then the previous write index can be shrunk.

A shrink operation:

  • Creates a new target index with the same definition as the source index, but with a smaller number of primary shards.
  • Hard-links segments from the source index into the target index. If the file system does not support hard-linking, then all segments are copied into the new index, which is a much more time consuming process. Also if using multiple data paths, shards on different data paths require a full copy of segment files if they are not on the same disk since hardlinks do not work across disks.
  • Recovers the target index as though it were a closed index which had just been re-opened. Recovers shards to the .routing.allocation.initial_recovery._id index setting.

IMPORTANT: Indices can only be shrunk if they satisfy the following requirements:

  • The target index must not exist.
  • The source index must have more primary shards than the target index.
  • The number of primary shards in the target index must be a factor of the number of primary shards in the source index. The source index must have more primary shards than the target index.
  • The index must not contain more than 2,147,483,519 documents in total across all shards that will be shrunk into a single shard on the target index as this is the maximum number of docs that can fit into a single shard.
  • The node handling the shrink process must have sufficient free disk space to accommodate a second copy of the existing index.

Split an index Generally available; Added in 6.1.0

POST /{index}/_split/{target}

All methods and paths for this operation:

PUT /{index}/_split/{target}

POST /{index}/_split/{target}

Split an index into a new index with more primary shards.

  • Before you can split an index:

  • The index must be read-only.

  • The cluster health status must be green.

You can do make an index read-only with the following request using the add index block API:

PUT /my_source_index/_block/write

The current write index on a data stream cannot be split. In order to split the current write index, the data stream must first be rolled over so that a new write index is created and then the previous write index can be split.

The number of times the index can be split (and the number of shards that each original shard can be split into) is determined by the index.number_of_routing_shards setting. The number of routing shards specifies the hashing space that is used internally to distribute documents across shards with consistent hashing. For instance, a 5 shard index with number_of_routing_shards set to 30 (5 x 2 x 3) could be split by a factor of 2 or 3.

A split operation:

  • Creates a new target index with the same definition as the source index, but with a larger number of primary shards.
  • Hard-links segments from the source index into the target index. If the file system doesn't support hard-linking, all segments are copied into the new index, which is a much more time consuming process.
  • Hashes all documents again, after low level files are created, to delete documents that belong to a different shard.
  • Recovers the target index as though it were a closed index which had just been re-opened.

IMPORTANT: Indices can only be split if they satisfy the following requirements:

  • The target index must not exist.
  • The source index must have fewer primary shards than the target index.
  • The number of primary shards in the target index must be a multiple of the number of primary shards in the source index.
  • The node handling the split process must have sufficient free disk space to accommodate a second copy of the existing index.

Required authorization

  • Index privileges: manage

Path parameters

  • index string Required

    Name of the source index to split.

  • target string Required

    Name of the target index to create.

Get index statistics Generally available; Added in 1.3.0

GET /{index}/_stats/{metric}

All methods and paths for this operation:

GET /_stats

GET /{index}/_stats
GET /_stats/{metric}
GET /{index}/_stats/{metric}

For data streams, the API retrieves statistics for the stream's backing indices.

By default, the returned statistics are index-level with primaries and total aggregations. primaries are the values for only the primary shards. total are the accumulated values for both primary and replica shards.

To get shard-level statistics, set the level parameter to shards.

NOTE: When moving to another node, the shard-level statistics for a shard are cleared. Although the shard is no longer part of the node, that node retains any node-level statistics to which the shard contributed.

Required authorization

Unfreeze an index Deprecated Generally available; Added in 6.6.0

POST /{index}/_unfreeze

When a frozen index is unfrozen, the index goes through the normal recovery process and becomes writeable again.

Required authorization

  • Index privileges: manage

Path parameters

  • index string Required

    Identifier for the index.

Query parameters

  • allow_no_indices boolean

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are: all, open, closed, hidden, none.

    Supported values include:

    • all: Match any data stream or index, including hidden ones.
    • open: Match open, non-hidden indices. Also matches any non-hidden data stream.

Move to a lifecycle step Generally available; Added in 6.6.0

POST /_ilm/move/{index}

Manually move an index into a specific step in the lifecycle policy and run that step.

WARNING: This operation can result in the loss of data. Manually moving an index into a specific step runs that step even if it has already been performed. This is a potentially destructive action and this should be considered an expert level API.

You must specify both the current step and the step to be executed in the body of the request. The request will fail if the current step does not match the step currently running for the index This is to prevent the index from being moved from an unexpected step into the next step.

When specifying the target (next_step) to which the index will be moved, either the name or both the action and name fields are optional. If only the phase is specified, the index will move to the first step of the first action in the target phase. If the phase and action are specified, the index will move to the first step of the specified action in the specified phase. Only actions specified in the ILM policy are considered valid. An index cannot move to a step that is not part of its policy.

Required authorization

  • Index privileges: manage_ilm

Path parameters

  • index string Required

    The name of the index whose lifecycle step is to change

application/json

Body

  • current_step object Required

    The step that the index is expected to be in.

    • action string

      The optional action to which the index will be moved.

    • name string

      The optional step name to which the index will be moved.

    • phase string Required
  • next_step object Required

    The step that you want to run.
