This should maybe go into the FAQ...
When you run htsearch with no customization, on a large database, and
it gets a lot of hits, it tends to take a long time to process those hits.
Some users with large databases have reported much higher performance, for
searches that yield lots of hits, by setting the backlink_factor attribute
in htdig.conf to 0, and sorting by score. The scores calculated this
way aren't quite as good, but htsearch can process hits much faster when
it doesn't need to look up the docdb record for each hit, just to get the
backlink count, date or title, either for scoring or for sorting.
This affects 3.1.0b3 and up, but should be addressed better in 3.2, when
it comes out in a few months.
