             Summary: Maybe a DocIdSetIterator may implement Bits?
                 Key: LUCENE-8386
                 URL: https://issues.apache.org/jira/browse/LUCENE-8386
             Project: Lucene - Core
          Issue Type: Improvement
          Components: core/search
            Reporter: David Smiley


I was looking at ConjunctionDISI and noted the special case logic for DISI's of type BitSetIterator. It seems to only need the more minimal Bits interface though it makes references to BitSet specifically.   BitSetIterator is a concrete class; it would be nice if a DISI could either implement an optional interface to expose a Bits or perhaps implements Bits directly.  This would allow other/custom DISIs that can implement a Bits quickly without being forced to use BitSetIterator specifically.  Even DocIdSetIterator.all(...) could implement this.
