If the forum search tool would do an "and" on the words, it would help a lot in restricting the search results so a person doesn't have to look at many topics to find and answer. Allowing "and", "or", and phrases would be best. Good search tools are really important to solving problems.
It would help a lot to have an issue tracking mechanism that customers could work with. It would also help a lot to separate issues as on friendsofaw.com, but being able to do powerful searches is the most important thing.
