Get index API

Get index API

Returns information about one or more indices. For data streams, the API returns information about the stream’s backing indices.

  1. GET /my-index-000001

Before 7.0.0, the mappings definition used to include a type name. Although mappings in responses no longer contain a type name by default, you can still request the old format through the parameter include_type_name. For more details, please see Removal of mapping types.

Request

GET /<target>

Prerequisites

  • If the Elasticsearch security features are enabled, you must have the view_index_metadata or manage index privilege for the target data stream, index, or alias.

Path parameters

<target>

(Required, string) 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.

Query parameters

allow_no_indices

(Optional, 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.

Defaults to true.

expand_wildcards

(Optional, 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

    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 patterns are not accepted.

Defaults to open.

flat_settings

(Optional, Boolean) If true, returns settings in flat format. Defaults to false.

include_defaults

(Optional, Boolean) If true, return all default settings in the response. Defaults to false.

include_type_name

[7.0.0] Deprecated in 7.0.0. Mapping types have been deprecated. See Removal of mapping types. (Optional, boolean) If true, a mapping type is expected in the body of mappings. Defaults to false.

ignore_unavailable

(Optional, Boolean) If false, requests that target a missing index return an error. Defaults to false.

local

(Optional, 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

(Optional, time units) 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. Defaults to 30s.
