== Clear Cache

The clear cache API allows to clear either all caches or specific cached
associated with one ore more indices.

[source,js]
--------------------------------------------------
$ curl -XPOST 'http://localhost:9200/twitter/_cache/clear'
--------------------------------------------------

The API, by default, will clear all caches. Specific caches can be
cleaned explicitly by setting `filter`, `field_data` or `bloom` to
`true`.

All caches relating to a specific field(s) can also be cleared by
specifying `fields` parameter with a comma delimited list of the
relevant fields.

=== Multi Index

The clear cache API can be applied to more than one index with a single
call, or even on `_all` the indices.
