Sometimes you can use Google to search Mudcat. It doesn't always find what you're looking for, because not all threads have been indexed by Google. Just add "site:www.mudcat.org" (without quotes) to your search argument. For example, with the argument

     search suck site:www.mudcat.org

Google finds about 1,290 Mudcat threads where the words "search" and "suck" appear on the same page. It's even easier if you have Google's taskbar installed. You don't have to type "site:www.mudcat.org" - you just click "Current site" and it searches whatever website you already have loaded.

This can be really useful when you're searching a site that doesn't have its own search engine, or if you just don't want to take the time to figure out how their search works.
