Adrien Grand updated LUCENE-6303:
---------------------------------
Attachment: LUCENE-6303.patch
Here is a patch which:
- replaces CachingWrapperFilter with CachingWrapperQuery
- replaces FilterCache with QueryCache and caches weights instead of filters
- removes DocIdSet.isCacheable since this method is not used anymore
- adds built-in query caching to IndexSearcher (enabled by default): weights
in the query tree that do not need scores are cached.

>
> As part of the filter -> query migration, we should migrate the caching
> wrappers (including the filter cache).
> I think the behaviour should be to delegate to the wrapped query when scores
> are needed and cache otherwise like CachingWrapperFilter does today.
> Also the cache should ignore query boosts so that field:value^2 and
> field:value^3 are considered equal if scores are not needed.
