Get index

Introduced 1.0

You can use the get index API operation to return information about an index.

Path and HTTP methods

GET /<index>

Path parameters

Path parameters

The following table lists the available path parameters. All path parameters are optional.

Parameter Data type Description
<index> String A comma-separated list of indexes, data streams, or index aliases to which the operation is applied. Supports wildcard expressions (*). Use _all or * to specify all indexes and data streams in a cluster.

Query parameters

All parameters are optional.

Parameter Type Description
allow_no_indices Boolean Whether to ignore wildcards that don’t match any indexes. Default is true.
expand_wildcards String Expands wildcard expressions to different indexes. Combine multiple values with commas. Available values are all (match all indexes), open (match open indexes), closed (match closed indexes), hidden (match hidden indexes), and none (do not accept wildcard expressions), which must be used with open, closed, or both. Default is open.
flat_settings Boolean Whether to return settings in the flat form, which can improve readability, especially for heavily nested settings. For example, the flat form of “index”: { “creation_date”: “123456789” } is “index.creation_date”: “123456789”.
include_defaults Boolean Whether to include default settings as part of the response. This parameter is useful for identifying the names and current values of settings you want to update.
ignore_unavailable Boolean If true, OpenSearch does not include missing or closed indexes in the response.
local Boolean Whether to return information from only the local node instead of from the cluster manager node. Default is false.
cluster_manager_timeout Time How long to wait for a connection to the cluster manager node. Default is 30s.
