Perhaps you should try some spelling variations:
"motet" » "monet", "moret", "moet", "modet", "movet", "motst"
"motets" » "monets", "morets", "moets", "modets", "movets", "motsts"
"mote" » "mode", "move", "mots"
"motte" » "mitte"
"mottes" » "mittes", "mottoes", "mottets", "mottles"
"lotet" » "loten"

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 "mote") OR "motte") OR "more") OR (("motets" OR "mottes") OR "lotet")).
• Removing quotes may allow a broader search: (((( motet or mote ) or motte ) or more ) or (( motets or mottes ) or lotet )).
• Adding a wildcard symbol may retrieve word variants: (((("motet" or "mote") or "motte") or "more") or (("motets" or "mottes") or "lotet"))*.
