Well the crux of the problem is this:
Not only do you have to do scoring, but you have to perform some
filtering on the results (e.g. restrict, exclude, occasionally
sorting by title or date) and you don't know how many these will
remove from the batch.
Multiword searches are also very complicated because the scoring may
not be the same on all words. And to top it off, in version 3.2, the
words aren't scored until search-time.
However, in 3.2, you know how many word matches per document before
scoring. So you can estimate the score by the number of matches and
go from there, scoring after doing a multiword comparison. (Actually,
multiword searches could be faster too, but that's a bit offtopic.)
In short, there are a variety of problems, but if anyone wants to
help me solve them, htsearch performance can definitely be improved.
