Ok I can confirm it.
If you search for "sm7" (don't use quotes) in titles only you will get 1 search result (titled, "Advice on SM7")
Then go to the main forum page and go to the Microphones forum. If you do a find on page (Cntrl + F) or just scroll down to about the 15th post, you'll find the post titled, "SM7 -- or any dynamic....". This one wasn't picked up by the search.
Also search on titles only for "Studio Projects" and you'll get no results, yet on the Microphones Forum main page there are 3 posts with it in the title.
Also, I love this forum and don't want to be critical or bitch about it but it does suck that you can't search on anything with 2 or less characters. Stuff like C1, B3, SP....ah the life of a web developer....
