Although I will occasionally jump to a regular search engine, especially for a release of if I remember something reasonably likely to be unique to the thread but that is more likely because I have a nice search bar at the top of the browser, but I will have to +1 the search feature works and I especially enjoy the narrow by forum area and forum poster options. Combine it with filter options on forums themselves (although curiously if you start a thread and do not reply to it then it will not come up in threads you have replied to) and the ability to find all a member's posts (although I will agree the upgrade kind of gimped it, especially if they post in a lot of popular threads and stickies) and for the most part the average external search engine does not have a chance.
