== Clear Cache

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

// TEST[setup:twitter]

The API, by default, will clear all caches. Specific caches can be cleaned
explicitly by setting `query`, `fielddata` or `request`.

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.
