This depends. If you run the htdig program with -i, it will recreate
everything from scratch. If the old databases are there and you don't run
with -i, it will do the former.

Yeah, use 'at' or 'cron.' If you haven't heard of these, type "man cron"
or talk to a sysadmin who knows a little more about UNIX.

Position, yes. Structure (i.e. markup), yes. Ordering and proximity? Not

You bet. See the synonym file.

No. But I've tried out "natural language" searches, and I'm not convinced
they're actually "understanding" anything. They seem to simply be ignoring
very common words! (Yes, I'm sure there are people who will tell me I'm
wrong. I'm just telling you what seemed to come out of the "black box.")
So putting words like "the" and "what" in the bad_words file will ignore
them and should produce pretty good results.
