Clear Cache

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

POST /twitter/_cache/clear

The API, by default, will clear all caches. Specific caches can be cleaned explicitly by setting the query, fielddata or request url parameter to true.

POST /twitter/_cache/clear?query=true      
POST /twitter/_cache/clear?request=true    
POST /twitter/_cache/clear?fielddata=true

Cleans only the query cache

Cleans only the request cache

Cleans only the fielddata cache

In addition to this, all caches relating to a specific field can also be cleared by specifying fields url parameter with a comma delimited list of the fields that should be cleared. Note that the provided names must refer to concrete fields — objects and field aliases are not supported.

POST /twitter/_cache/clear?fields=foo,bar

Clear the cache for the foo an bar field

Multi Index

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