I run a intranet site for a support center. We use the site to post all our troubleshooting documentation to. The site has grown rather large and some of my users are complaining that they are having difficulties finding documents using the built in XOOPS search. I would like to find a program that would show me stats on common search words. Below is an example of a search from my access.log:

172.22.221.238 - - [18/Mar/2005:08:09:57 -0500] "GET /search.php?query=update&action=results HTTP/1.1" 200 10777

Anyone know of a stats program that will pull this information from the webserver's log file?

BTW, I am running Apache on Windows 2000.
