Perhaps you should try some spelling variations:
"motet" » "motets", "monet", "moret", "modet", "movet"
"motte" » "mitte"
"mottes" » "mittes", "mottoes", "mottets", "mottles"
"mote" » "more", "mode", "move"
"motes" » "mores", "modes", "moves", "motets", "notes"
"modes" » "model", "mode"
"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 "motte") OR "mote") OR ((("motes" OR "modes") OR "mottes") OR "lotet")).
• Removing quotes may allow a broader search: ((( motet or motte ) or mote ) or ((( motes or modes ) or mottes ) or lotet )).
• Adding a wildcard symbol may retrieve word variants: ((("motet" or "motte") or "mote") or ((("motes" or "modes") or "mottes") or "lotet"))*.
