>
> 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.
