===== Multiple data streams and indices

The get settings API can be used to get settings for more than one data stream or index with a
single call. To get settings for all indices in a cluster, you can use `_all` or `*` for `<target>`.
Wildcard expressions are also supported. The following are some examples:

[source,console]
--------------------------------------------------
GET /twitter,kimchy/_settings

GET /_all/_settings

GET /log_2013_*/_settings
--------------------------------------------------
// TEST[setup:twitter]
// TEST[s/^/PUT kimchy\nPUT log_2013_01_01\n/]

===== Filtering settings by name

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

[source,console]
--------------------------------------------------
GET /log_2013_-*/_settings/index.number_*
--------------------------------------------------
