The search function at the top does not always find items in event groups that are minimized.... so maybe this is a bug? Regardless, it would be nice to be able to search completely through all the events whether or not they're expanded, OR have the search function work 100% of the time.
It's impossible to expand all the events with one click, or key stroke... you have to manually go through your entire sheets, and THEN search for the search to work properly.
