Perhaps you should try some spelling variations:
"motet" » "lotet", "monet", "moret", "mottet", "modet", "movet"
"motets" » "lotets", "monets", "morets", "mottets", "modets", "movets"
"mote" » "motte", "mode", "move"
"modets" » "modeis", "modetn", "molodets"
"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 "motets") OR ("mote" OR "more")) OR ("modets" OR "lotes")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"motet\" or \"motets\") or (\"mote\" OR \"more\")) or (\"modets\" or \"lotes\"))".
• Removing quotes may allow a broader search: ((( motet or motets ) or ( mote OR more )) or ( modets or lotes )).
• Adding a wildcard symbol may retrieve word variants: ((("motet" or "motets") or ("mote" OR "more")) or ("modets" or "lotes"))*.
