Perhaps you should try some spelling variations:
"motet" » "lotet", "monet", "moret", "mottet", "modet"
"motets" » "lotets", "monets", "morets", "mottets", "modets"
"mote" » "motte", "more", "mode"
"motes" » "mottes", "mores", "modes", "moves", "moses"
"mores" » "cores", "pores"

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