If you want plug and play with minimal work http://siwsh-e.org provides the GNU data search engine. It will index almost anything (web content, Word docs, PDF), stems, etc, etc. You can write a plugin for it so it can index anything. It is currently used on most of the GNU sites for search. C, fast and stable. As a bonus all the templating/output stuff is perl so all you really need to do is edit TemplateDefault.pm and you can make it look like you wrote if spcifically for your site.
