Empty search lists all tunes. Asterisk (*) functions as a wildcard. For example, "*saari" will return all tunes that are from places where saari forms the last part of the place name such as 'Viitasaari'.
Combined search enables one to use several search criteria in one query. Specific search contains more specific search criteria. For example, you can search using keywords contained in the lyrics, or for tunes from certain regions.
