Perhaps you should try some spelling variations:
\"motet\" » \"motets\", \"mote\", \"monet\"
\"lotet\" » \"loten\"
\"lotets\" » \"lotens\", \"motets\", \"lotes\"
\"morets\" » \"moretus\", \"forets\", \"moreto\"

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

• Removing quotes may allow a broader search: (( motet or lotet ) or ( morets or lotets )).
