> 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.
