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