If you click the "Search" link and type your query right into that first box, the default search behavior is 'Search Entire Thread'. Instead, click on 'Advanced Search', type your query in and select 'Search Titles Only'.
Then again, I only came to realize that because I took a little 'time' to figure out why a thread I saw a day ago wasn't coming up when I was searching for keywords I knew for sure were in the title. I dunno - seems like too many people give up waaaay too easy in searching for their answer, especially if said answer isn't on the first page of a sub-forum, or isn't the first result returned from the search engine.
Laziness - it's the next epidemic.
P.S. I feel bad for the mods...you guys are doing a great job, but your numbers are a bit thin compared to the amount of posting. Stay sane, lol.
