Perhaps you should try some spelling variations:
"motet" » "motets", "lotet", "mote"
"moret" » "moreto", "mores", "morel"
"mottet" » "mottets", "mouttet", "motte"
"motes" » "motets", "notes", "modes"
"lotets" » "motets", "lotet", "lotes"

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 "moret") OR "mottet") OR "more") OR ("motes" OR "lotets")).
• Removing quotes may allow a broader search: (((( motet or moret ) or mottet ) or more ) or ( motes or lotets )).
• Adding a wildcard symbol may retrieve word variants: (((("motet" or "moret") or "mottet") or "more") or ("motes" or "lotets"))*.
