Is it possible to change this from 4 characters to 3 characters......at least for title searches b/c there are alot of terms that you can't search for b/c they are too short.
I do think you have to rebuild the index or something, b/c it is not finding old messages. However it did find the test message I just made with MSM in the title. Even if you can't it will be a good feature going forward.
