== Clear Cache

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

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. Note that the provided names must refer to concrete
fields -- objects and field aliases are not supported.

=== Multi Index

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