I'm not sure if anyone else has had these problems but I assume they have. I tried searching for a thread on GM, and I wrote a long title, but I got an error page that said:
The search term you specified (is) is under the minimum word length (3) and therefore will not be found. Please make this term longer.
What I searched was
more than 3 words, too. The same happened when trying to use the search item on a specific thread.
