I think wordzilla is taking an extended vacation from updating, but i know that the search works unchanged from previous smf 1.1x editions, so if you can make the changes manually it will work.

As for integrating it into v2 that might be more effort.. It would be nice if someone could get together with wordzilla and port it to version 2.

they improved the search in smf2 and seemed to incorporate some of the ideas, but i dont think they used the code or added all the features.
