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.

Query parameters

• allow_no_indices boolean

  A setting that does two separate checks on the index expression. If false, the request returns an error (1) if any wildcard expression (including _all and *) resolves to zero matching indices or (2) if the complete set of resolved indices, aliases or data streams is empty after all expressions are evaluated. If true, index expressions that resolve to no indices are allowed and the request returns an empty result.

• expand_wildcards string | array[string]

  Type of index that wildcard expressions 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.

  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 concrete (non-wildcarded) index, alias, or data stream that is missing, closed, or otherwise unavailable. If true, unavailable concrete targets are silently ignored.

• 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. 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.

• features string | array[string] Generally available; Added in 8.1.0
