Your right - a search on aubin failed to find the words, presumably the thread is too recent to be indexed. Personally my first choice is always to use the Filter with Age set to All - it's a lot faster; of course if the song was posted without the search word(s) in the title it won't find it. In this case aubin works fine. As it was I also knew the thread had just dropped off the bottom, so I just set the age to 3 days and refreshed to find it with no searching at all!
