Perhaps you should try some spelling variations:
"motet" » "lotet", "moret", "moet", "mottet", "modet", "movet"
"motets" » "lotets", "morets", "moets", "mottets", "modets", "movets"
"monet" » "monnet", "moneta", "monete"
"mote" » "motte", "mode", "move"
"motes" » "mottes", "modes", "moves", "moses"

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