Perhaps you should try some spelling variations:
"motet" » "lotet", "monet", "moret", "mottet", "movet"
"motets" » "lotets", "monets", "morets", "mottets", "movets"
"mote" » "motte", "more", "move"
"mode" » "more"
"modes" » "mores", "model"

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