Hi all,
I am working on implementing a new Query, Weight and Scorer that
is expensive to run. I'd like to limit the number of documents I
run this query on by first building a candidate set of documents
with a boolean query. Once I have that candidate set, I was hoping
I could build a filter off of it, and issue that along with my
expensive query. However, after reading the code I see that
filtering is done during the search, and not before hand.
Correct. I suppose you mean the filtering code in IndexSearcher?
Yes, that's exactly what I mean.
As Grant pointed out, this code was recently changed
by LUCENE-584.
I was referring to the (current trunk) code including this
change that uses skipTo() on a DocIdSetIterator obtained
from the Filter. Sorry for any confusion on this.
That clears things up alot :)
I kept looking at the code trying to figure out how it didn't filter
after scoring. I'll download the latest code and look.
Thanks,

Matt
