Too much time, almost 3 minutes!!! I don't know why. However I usually don't
start httpd on my RH. I start it only when I need to test htdig.....I noticed
that I need to relaunch rundig to have the best performances

Fine!! These are good news....In this way I could put the files I need

:-))) You are great!!! I found italian ispell dictionary, but I don't know
how install it...I think that the instructions I found inside the package
aren't for htdig, are it?

:-)) Yes, I know. I'm just trying to understand that script to best customize
it for my needs :-).....I'm also trying to understand which databases are
created by each program....so, I could understand if there's something that
doesn't work fine just looking the databases size.

Hmmmm, I'm sorry, but I can't understand what does "indexing from scratch"
mean...:-( could you better explain what were you saying?
I've a problem too, though I'm using the -a flag, I can't succeed in
searching anything when I launch rundig....where's the mistake? If I use the
-a flag, does htsearch automatically manage the search using the .work
database?
Thank you very much for your help :-)
