The Filter works only for thread titles. The Alphabetical listing for Digital Tradition tunes works pretty well, if you know the first word of the song title. Once you've brought up a page of the DT title list, find your song by using your browser's "Find" utility [CTRL-F].
When using the "Lyrics & Knowledge Search" (SuperSearch), you can search for a partial word by replacing the unknown part with an asterisk. If you were looking for "How Much Is That Doggie in the Window," the best word to use for thinking is Doggie, because very few people other than Patti Page are dorky enough to use a word like that. Trouble is, did Patti spell it "doggie" or "doggy"? search for dogg* or much is that dogg*, and it should come up (dogg* will give you far better results than dog*).
The asterisks don't work in the filter or the [CTRL-F] utility. They search for exactly what you type, and don't need asterisks.
Hope that helps. Do take a look at the FAQ (frequently asked questions), particularly the first message of the FAQ, for search advice.
