Cache Management
Caching is used so that the creation of duplicate results aren't attempted. While duplicate results are not permitted at a DBMS level, caching makes plugins more efficient in managing this and reduce unnecessary interaction with the backend database.
From time-to-time you may want to clear the cache of a plugin. Perhaps you deleted a result accidentally or you are testing a plugin, either way even if a result is deleted it is still stored in cache. To clear the cache for a specific plugin, navigate to Tasks > Manage Cache. A screenshot of this page is shown below:
