Go to your LW Library window & select each of all your folders. All songs that appear in there & are coloured black text means they are being shared. So if it's in there you did it right! Sometimes after adding a new folder to share you need to press the Refresh button in the Lib window.
You cannot search your own files using LW. It's not designed to do that.
