Perhaps you should try some spelling variations:
"motet" » "motets", "lotet", "monet", "mottet", "moret", "modet"
"moreto" » "moreton", "moreno"
"mottet" » "mottets", "mouttet", "motte"
"mote" » "motte", "more", "mode"
"motes" » "mottes", "mores", "modes", "motets", "notes"
"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 "moreto") OR "mottet") OR "mote") OR ("motes" OR "lotets"))*.
• Removing quotes may allow a broader search: (((( motet or moreto ) or mottet ) or mote ) or ( motes or lotets ))*.
