If you are running on a UNIX-based web server, there is a freeware search
tool called HTDIG that will index PDF files, as well as HTML and text files.
I'm using it on our intranet site a work. It requires a bit of technical
skill to set up (it has to be compiled before you can use it) and you have
to edit the templates for the search pages, but this is pretty much standard
for any search tool. It's actually easier to set up than the search tool
that comes with IIS.
