Perhaps you should try some spelling variations:
motet » lotet, monet, moret, mottet, modet
motets » lotets, monets, morets, mottets, modets
mottet » mouttet, motte, cottet
mottets » mouttets, mottes, cottets
mote » motte, more, mode
lopes » lopez, hopes, lope

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( (motet OR mottet) OR mote ) OR (( (motets OR mottets) OR moves ) OR lopes )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (motet or mottet) or mote ) or (( (motets OR mottets) or moves ) or lopes ))".
• Adding a wildcard symbol may retrieve word variants: (( (motet or mottet) or mote ) or (( (motets OR mottets) or moves ) or lopes ))*.
