[[search-search]]
== Search

The search API allows to execute a search query and get back search hits
that match the query. The query can either be provided using a simple
<<search-uri-request,query string as a parameter>>, or using a
<<search-request-body,request body>>.

=== Multi-Index, Multi-Type

All search APIs can be applied across multiple types within an index, and
across multiple indices with support for the
<<multi-index,multi index syntax>>. For
example, we can search on all documents across all types within the
twitter index:

[source,js]
--------------------------------------------------
$ curl -XGET 'http://localhost:9200/twitter/_search?q=user:kimchy'
--------------------------------------------------

We can also search within specific types:

[source,js]
--------------------------------------------------
$ curl -XGET 'http://localhost:9200/twitter/tweet,user/_search?q=user:kimchy'
--------------------------------------------------

We can also search all tweets with a certain tag across several indices
(for example, when each user has his own index):

[source,js]
--------------------------------------------------
$ curl -XGET 'http://localhost:9200/kimchy,elasticsearch/tweet/_search?q=tag:wow'
--------------------------------------------------

Or we can search all tweets across all available indices using `_all`
placeholder:

[source,js]
--------------------------------------------------
$ curl -XGET 'http://localhost:9200/_all/tweet/_search?q=tag:wow'
--------------------------------------------------

Or even search across all indices and all types:

[source,js]
--------------------------------------------------
$ curl -XGET 'http://localhost:9200/_search?q=tag:wow'
--------------------------------------------------
