Mark Miller commented on LUCENE-1483:
-------------------------------------
I'll put up another patch soon with those changes. All look correct. I wasn't
sure about maxdoc or numdoc (not that I spent much time thinking about it)
because the fieldcache loads up all the deleted docs - for things like the
terms array to be mapped to, that depends on maxdoc. But then how many hits are
likely to end up in the queue is more related to numdocs. Switched it to
numdocs.
Still have to wrap up the custom comparator, but a comparatorpolicy changes
things there. If you can set a custom comparatorpolicy (move it to sort?), than
you can easily put in any custom comparators.
