Perhaps you should try some spelling variations:
"motet" » "lotet", "monet", "moret", "modet", "movet"
"motets" » "lotets", "monets", "morets", "modets", "movets"
"mote" » "more", "mode", "move"
"motes" » "mores", "modes", "moves", "notes"
"motte" » "mitte"
"lotets" » "lotet", "lotens", "lotete"
"lotes" » "notes", "votes", "lopes"

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 ((("motets" OR "lotets") OR "motes") OR "lotes")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"motet\" or (\"mote\" OR \"motte\")) or (((\"motets\" or \"lotets\") or \"motes\") or \"lotes\"))".
• Removing quotes may allow a broader search: (( motet or ( mote OR motte )) or ((( motets or lotets ) or motes ) or lotes )).
• Adding a wildcard symbol may retrieve word variants: (("motet" or ("mote" OR "motte")) or ((("motets" or "lotets") or "motes") or "lotes"))*.
