[jira] [Updated] (LUCENE-6303) CachingWrapperFilter -> CachingWrapperQuery

["Adrien Grand (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LUCENE-6303?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.
