Path parametersedit

<index>

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

Query parametersedit

allow_no_indices

(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.

Defaults to true.

expand_wildcards

(Optional, string) Controls what kind of indices that wildcard expressions can expand to. Multiple values are accepted when separated by a comma, as in open,hidden. Valid values are:

all
Expand to open and closed indices, including hidden indices.
open
Expand only to open indices.
closed
Expand only to closed indices.
hidden
Expansion of wildcards will include hidden indices. Must be combined with open, closed, or both.
none
Wildcard expressions are not accepted.

Defaults to open.

flat_settings
(Optional, boolean) If true, returns settings in flat format. Defaults to false.
include_defaults
(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.
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.
