Get index settings Generally available

GET /{index}/_settings/{name}
Api key auth Basic auth Bearer auth

All methods and paths for this operation:

GET /_settings

GET /_settings/{name}
GET /{index}/_settings
GET /{index}/_settings/{name}

Get setting information for one or more indices. For data streams, it returns setting information for the stream's backing indices.

Required authorization

  • Index privileges: view_index_metadata

Path parameters

  • index string | array[string] Required

    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.

  • name string | array[string] Required

    Comma-separated list or wildcard expression of settings to retrieve.

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.

  • flat_settings boolean

    If true, returns settings in flat format.

  • ignore_unavailable boolean

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

  • include_defaults boolean

    If true, return all default settings in the response.

  • 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.

          • index_routing string

            Value used to route indexing operations to a specific shard. If specified, this overwrites the routing value for indexing operations.

          • is_hidden boolean

            If true, the alias is hidden. All indices for the alias must have the same is_hidden value.

            Default value is false.

          • is_write_index boolean

            If true, the index is the write index for the alias.

            Default value is false.

          • routing string

            Value used to route indexing and search operations to a specific shard.

          • search_routing string

            Value used to route search operations to a specific shard. If specified, this overwrites the routing value for search operations.
