Path parametersedit

<index>

(Optional, string) Comma-separated list or wildcard expression of index names used to limit the request.

Important

This parameter does not distinguish between an index name and alias, i.e. status code 200 is also returned if an alias exists with that name.

Query parametersedit

(Optional, boolean) If true, the request does not return an error if a wildcard expression or _all value retrieves only missing or closed indices.

This parameter also applies to index aliases that point to a missing or closed index.

Expand to open and closed indices.

(Optional, string) If true, return all default settings in the response. Defaults to false.
ignore_unavailable
(Optional, boolean) If true, missing or closed indices are not included in the response. Defaults to false.
