htdig

I'm trying to set up htdig. Well actually i did set it up but I had only 1GB free on the /opt filesystem where htdig was installed. The indexing started and never actually ended cause the disk got full and everything went down. So I would like to ask you... 1) How big is the htdig database after completion? (I have 44GB on another filesystem so maybe move it there) 2) How long does it take for indexing to be completed and is htdig that smart so that it won't go through the whole site every night? Spyros
