Wouldn't hurt I suppose - but test-core and test-contrib are probably
sufficient. I wasn't very clear with that comment. I was just saying, as

OK I I just left that new one off. So you have to run "ant test-core

4) An additional possibly contrib module is caching the results of
TermQueries. In looking at the TermQuery code would we need to cache the
entire docs and freqs as arrays which would be a memory hog?

I'm interested in merging cached bitsets and field caches. While this may

I'm not sure how big a win this'd be, since the OS will cache those in
RAM and the CPU cost there (to pull from OS's cache and reprocess) is
maybe not high.
Optimizing search is interesting, because it's the wicked slow queries
that you need to make faster even when it's at the expense of wicked

Bobo is a faceting engine that uses custom field caches and sometimes cached
bitsets rather than relying exclusively on bitsets to calculate facets. It
is useful where many facets (50+) need to be calculated and bitset caching,

viable in your situation...
The delete by query is a separate problem which I haven't fully
explored yet. Tracking the segment genealogy is really an
interim step for merging field caches before column stride
fields gets implemented.
How do you create a Lucene Filter to check if a field has a value? It is
part for a ChainedFilter that I am creating.
