I've been meaning to build a search feature for a while now, as I'm frequently trying to look up stuff I've written on here. After doing a little research and discovering mysql's fulltext search feature, I threw it together and am quite pleased with the results.

Right now, I have the search feature on the right-side navigation of my site. Try it out. And if you want to narrow your search results, click on the link titled "operators" to see how to modify your search.

The search is currently restricted to the message body, but I'll modify it shortly to include the message titles.
