Searchable archives?

This may have been asked before, but there were a lot of threads to go through :) I have gotten so behind on the mailing list, and I was glad to see that the archives are available online. Whatever you are using to generate the archives pages... Is there a way to make it searchable?

Also, I just jumped from beta 4 to RC5, and was pleased with the bug fixes and everything else. Thanks again Heinrik!
