Perhaps you should try some spelling variations:
"motet" » "lotet", "monet", "moet", "mottet", "moret", "modet"
"motets" » "lotets", "monets", "moets", "mottets", "morets", "modets"
"moret" » "moreto", "mores", "morel"
"morets" » "moretos", "moress", "morels", "moretus", "forets", "moreto"
"mote" » "motte", "more", "mode"
"moets" » "meets", "poets", "moems"
"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 "moret") OR "mote") OR ((("motets" OR "moets") OR "morets") OR "lotets")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"motet\" or \"moret\") or \"mote\") or (((\"motets\" OR \"moets\") or \"morets\") or \"lotets\"))".
• Removing quotes may allow a broader search: ((( motet or moret ) or mote ) or ((( motets OR moets ) or morets ) or lotets )).
• Adding a wildcard symbol may retrieve word variants: ((("motet" or "moret") or "mote") or ((("motets" OR "moets") or "morets") or "lotets"))*.
