Ability to search a specific forum for a specific string?

I am sure that I am just overlooking something in the page template, but I wanted to search the Buy/Sell/Trade forum for a specific razor to see if it was offered for sale (instead of wading through all the posts). I didn't see a way to do that. Is there a way to do that?



I looked through the advanced search and didn't see a way to specify the a forum to restrict the searches.



I did see the boxes to filter the subject prefixes in the BST forum, but that is all I found.



Thanks!
