It would also be very helpful to have a look through the rank.c code.
It needs some work.
It would be great to find a way to limit the effect of vastly different
sized documents (rank is mostly based on the word frequency which does
not work when file sizes are very different. An example can be seen at
http://search.apache.org -- search for "install" and you end up with
mailing list archives and the large CHANGES file at the top (type in
"installation" and it works better).
Fuzzy searching doesn't really help. Try "install" with "sound-alike"
There's code in rank.c to take into consideration total words in the
file (IgnoreTotalWordCountWhenRanking), but I have not found it that
much better for ranking.
