Subject [jira] Created: (JCR-791) Cache BitSet per IndexReader in MatchAllScorer
Date Wed, 14 Mar 2007 13:08:09 GMT
Cache BitSet per IndexReader in MatchAllScorer

                 Key: JCR-791
                 URL: https://issues.apache.org/jira/browse/JCR-791
             Project: Jackrabbit
          Issue Type: Improvement
          Components: query
            Reporter: Marcel Reutegger
            Priority: Minor

The BitSets created in MatchAllScorer should be cached per IndexReader. This enhancement should
also take care that the supplied IndexReader may in fact be a CombinedIndexReader or a CachingMultiReader
with multiple contained IndexReaders. To achieve a good cache efficiency the BitSets must
be cached per contained IndexReader and combined later.
