Perhaps you should try some spelling variations:
"motet" » "lotet", "moret", "moet", "mottet", "modet"
"motets" » "lotets", "morets", "moets", "mottets", "modets"
"monet" » "monnet", "moneta", "monete"
"mote" » "motte", "more", "mode"
"lotets" » "lotet", "lotes", "lotens"

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