Adrien Grand 95f46f1212 Docs: Use the new experimental annotation.
We now have a very useful annotation to mark features or parameters as
experimental. Let's use it! This commit replaces some custom text warnings with
this annotation and adds this annotation to some existing features/parameters:
 - inner_hits (unreleased yet)
 - terminate_after (released in 1.4)
 - per-bucket doc count errors in the terms agg (released in 1.4)

I also tagged with this annotation settings which should either be not needed
(like the ability to evict entries from the filter cache based on time) or that
are too deep into the way that Elasticsearch works like the Directory
implementation or merge settings.

[[search-request-body]]
== Request Body Search
The search request can be executed with a search DSL, which includes the
<<query-dsl,Query DSL>>, within its body. Here is an
example:
[source,js]
--------------------------------------------------
$ curl -XGET 'http://localhost:9200/twitter/tweet/_search' -d '{
"query" : {
"term" : { "user" : "kimchy" }
}
}
'
--------------------------------------------------
And here is a sample response:
[source,js]
--------------------------------------------------
{
"_shards":{
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits":{
"total" : 1,
"hits" : [
{
"_index" : "twitter",
"_type" : "tweet",
"_id" : "1",
"_source" : {
"user" : "kimchy",
"postDate" : "2009-11-15T14:12:12",
"message" : "trying out Elasticsearch"
}
}
]
}
}
--------------------------------------------------

=== Parameters
[horizontal]
`timeout`::
A search timeout, bounding the search request to be executed within the
specified time value and bail with the hits accumulated up to that point
when expired. Defaults to no timeout. See <<time-units>>.
`from`::
The starting from index of the hits to return. Defaults to `0`.
`size`::
The number of hits to return. Defaults to `10`.
`search_type`::
The type of the search operation to perform. Can be
`dfs_query_then_fetch`, `dfs_query_and_fetch`, `query_then_fetch`,
`query_and_fetch`. Defaults to `query_then_fetch`. See
<<search-request-search-type,_Search Type_>> for more.
`query_cache`::
Set to `true` or `false` to enable or disable the caching
of search results for requests where `?search_type=count`, ie
aggregations and suggestions. See <<index-modules-shard-query-cache>>.
`terminate_after`::
experimental[] The maximum number of documents to collect for each shard,
upon reaching which the query execution will terminate early. If set, the
response will have a boolean field `terminated_early` to indicate whether
the query execution has actually terminated_early. Defaults to no
terminate_after.
Out of the above, the `search_type` and the `query_cache` must be passed as
query-string parameters. The rest of the search request should be passed
within the body itself. The body content can also be passed as a REST
parameter named `source`.
Both HTTP GET and HTTP POST can be used to execute search with body. Since not
all clients support GET with body, POST is allowed as well.
