This is off topic (a bit) so I apologize in advanced.
This is where a dedicated search page with an excerpt under each title would greatly help. It gives me a better idea of whether or not this topic is the one I want, as there is an excerpt there to help me make my decision.
Back on Topic:
I struggle with the current search implementation. I spend way too much time trying different search terms/multiple terms to try and find what I want. Then I go to the category I thought it may be in, and search only that category. Keep this going for several minutes until I either 1) give up, or 2) find what I was looking for.
New users won’t spend as much time as I do.
