> I think OpenBitSet is trying to satisfy too many audiences, and it's
> confusing/error-proned as a result.  It has int/long variants of many
> methods.  Some methods require in-bound access, others don't; of those
> others, some methods auto-grow the bits, some don't.  OpenBitSet
> doesn't always know its numBits.
> I'd like to factor out a more "focused" bit set impl whose primary
> target usage is a cached Lucene Filter, ie a bit set indexed by docID
> (int, not long) whose size is known and fixed up front (backed by
> final long[]) and is always accessed in-bounds.
