Any web folks have a suggestions for running a search engine on a web server?

I'd like to offer local search of all the captions and presentation files on https://media.defcon.org and https://infocon.org but don't want big additional security concerns.

media.defcon.org

All DEF CON video presentations, music, documentaries, pictures, villages, and Capture The Flag data that can be found.
