All the publications and all the composer pages are searched. Searching for violin will find violin and violins, while iol will match viol, violins, Iolanthe, etc. To find pieces for say soprano, flute, and bass, search for soprano, flute, bass (note the commas between terms).

Diacritics are ignored and non-roman letters are simplified. Thus Medee matches Médee, François matches Francois, flûte matches flute, Handel matches Händel, Helsingør matches Helsingor (often known as Elsinore in English), etc.
