If you are using the search functions on the forums and you keep getting no results try selecting 'Any poster' in the By User section.

The default is 'Search-All-Members only'  You would think that this means all members posts but it doesn't    It means search members names only.  So unless someone's user name has the search word, you get no results.

This may be fixed with a later update to be more sensible but, for now, just broaden the search by selecting 'Any poster' instead and then it works fine.
