Move deletes to a top level boolean AND NOT query
Is anyone working on this? I can't find a patch. I'll start one unless
someone has something to post.

Does the LUCENE-1536 patch create a compound filter out of multiple
filters? Then the compound filter is passed down to TermQuery? What is the
status of LUCENE-1345?

I don't think anyone is working on it..., because It looks like this
is a real hit to performance (the results I posted on LUCENE-1476).
We shouldn't do it.
And, in fact, we should consider doing the reverse: taking filters
that are now applied via iteration and instead distributing them down
to each TermQuery (LUCENE-1536) via random-access API (if the filter
can support it); that can give much better performance.
However I need to redo these tests once LUCENE-1345 is in.
