Perhaps you should try some spelling variations:
motet » lotet, monet, moret, modet, movet
motets » lotets, monets, morets, modets, movets
moreto » moreton, moreno
mote » more, mode, move
motte » mitte

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 motets) OR moreto) OR ( mote OR motte ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "( ((motet OR motets) or moreto) or ( mote or motte ))*".
