Full-text searching of several sites (Question)

[Jen McLeod]

Hello there!

Has anyone attempted to set up full-text searching of about 
20 or 25 sites, none of which are search engines themselves?
These could be universities, businesses, orgs, what have you.

I have someone who wants to be able to do full-text searching of 
20 sites and ONLY those 20 sites retrieving relevant information
all at once.  He'd like to set up something locally that will
let him do the searching.  

Information on commercial "extraction services" would also be
welcome, but this fellow is a real "do-it-yourselfer".  

If you can give me any pointers, tips, ideas, comments, general
information on either of the above, it would be most appreciated!

I'll summarize for the list...

thanks!
