Query parametersedit

allow_no_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 all.

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.
master_timeout
(Optional, time units) Specifies the period of time 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.

Examplesedit

Multiple indicesedit

The get settings API can be used to get settings for more than one index with a single call. To get settings for all indices you can use _all for <index>. Wildcard expressions are also supported. The following are some examples:

GET /twitter,kimchy/_settings

GET /_all/_settings

GET /log_2013_*/_settings

Filtering settings by nameedit

The settings that are returned can be filtered with wildcard matching as follows:

GET /log_2013_-*/_settings/index.number_*
