Michael:

   Actually this is not what I meant.

   It was discussion that was wrapped in  Lucene-1345 where I posted some optimizations for Conjunction and Disjunction Scorers and some numbers. Because of the confusion of what  Lucene-1345 is, the loop was never closed. I am just writing to follow up.

Thanks

right?

I would love to see these in Lucene... P4Delta, which Paul has started
under LUCENE-1410, is clearly a win, but is a biggish change to Lucene
since all offsets would need to become "blockID + offsetWithinBlock".
LUCENE-1458 (further steps flexible indexing) tries to make things
generic enough that P4Delta can simply be a different codec.

On the logic operators for combining DocIDSets... how do these differ
from what we already do in BooleanScorer[2]?  (I haven't had a chance
to get a good look at Kamikaze yet).
