The API, by default, will clear all caches. Specific caches can be
|
2014-01-09 15:08:45 -05:00
|
|
|
cleaned explicitly by setting `filter`, `field_data` or `id_cache` to
|
2013-08-28 19:24:34 -04:00
|
|
|
`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.
