------------------------------------
Attachment: LUCENE-3593.patch
next iteration. I added a AIOOBE to all the match methods to make the interface
happy. I think we should fix this as uwe mentioned. Uwe, can you create a
subtask / issue to fix this.. I think you already on it no? I added some more
optimizations if the Bits is instanceof MatchNoBits / MatchAllBits respectively
I return null instead of the DocIdSetIterator when appropriate. all test pass..
I think it's ready..
