This is a general topic, but I did not find any "Forum" specific search option. The only search box that shows up is for the entire intel.com site at the very-top. It seems that "search" should be just before "new-topic"!
Use http://software.intel.com/en-us/forum to find all entries of forums, which is one of "platform & technology" discussion, or "Intel software developement tools" discussion.
