=== Get Settings API

[id="{upid}-{api}-request"]
==== Get Settings Request

A +{request}+ requires one or more `index` arguments:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request]
--------------------------------------------------
<1> The index whose settings we should retrieve

==== Optional arguments
The following arguments can optionally be provided:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-names]
--------------------------------------------------
<1> One or more settings that be the only settings retrieved.  If unset, all settings will be retrieved

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-include-defaults]
--------------------------------------------------
<1> If true, defaults will be returned for settings not explicitly set on the index

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-indicesOptions]
--------------------------------------------------
<1> Setting `IndicesOptions` controls how unavailable indices are resolved and
how wildcard expressions are expanded

[id="{upid}-{api}-response"]
==== Get Settings Response

The returned +{response}+ allows to retrieve information about the
executed operation as follows:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-response]
--------------------------------------------------
<1> We can retrieve the setting value for a particular index directly from the response as a string
<2> We can also retrieve the Settings object for a particular index for further examination
<3> The returned Settings object provides convenience methods for non String types

If the `includeDefaults` flag was set to true in the +{request}+ the
behavior of +{response}+ will differ somewhat.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-defaults-response]
--------------------------------------------------
<1> Individual default setting values may be retrieved directly from the +{response}+
<2> We may retrieve a Settings object for an index that contains those settings with default values
