As an aside, personally I use the Sphinx full-text search engine. While it's not entirely perfect (I would LOVE to have delta merging to not cost as much IO), there's practically no cost to searching. One of my biggest pet peeves for message board software was the search timer because all the search algorithms sucked. It was either something like this or just plain used MySQLs FULLTEXT feature which is horrible for 1GB+ pure text data. So when I wrote my own forum software, I used Sphinx for zero-cost searching. http://forum.fangamer.com/forum/search/ http://forum.fangamer.com/forum/search/
