Perhaps you should try some spelling variations:
"motet" » "lotet", "monet", "moret", "mottet", "movet", "motst"
"motets" » "lotets", "monets", "morets", "mottets", "movets", "motsts"
"mote" » "motte", "move", "mots"
"motes" » "mottes", "moves", "motss", "modes", "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 (("mote" OR "mode") OR "more")) OR (("motets" OR "motes") OR "notes")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"motet\" or ((\"mote\" OR \"mode\") or \"more\")) or ((\"motets\" or \"motes\") or \"notes\"))".
• Removing quotes may allow a broader search: (( motet or (( mote OR mode ) or more )) or (( motets or motes ) or notes )).
• Adding a wildcard symbol may retrieve word variants: (("motet" or (("mote" OR "mode") or "more")) or (("motets" or "motes") or "notes"))*.
