I tried it a couple of times just now. It pulled up more posts than the standard search did for the same item but it didnt pull up the same posts. I think it will work out well once we all figure out which details to include in the search.
I played with it a little more last night. It seems to work much better than the standard search if you put in a little more info. example: NEF .243 will return a blue million posts that may or may not be what you want. If you enter NEF .243 youth model rifle, it will pull up more specific posts. Just give as much info as you can on the search and it will return good results.
