Perhaps you should try some spelling variations:
"motet" » "lotet", "mote", "monet"
"motets" » "lotets", "motes", "monets"
"moret" » "moreto", "mores", "morel"
"morets" » "moretos", "moress", "morels", "moretus", "forets", "moreto"
"mode" » "more"
"lotes" » "notes", "votes", "lopes"

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 "mode") OR (("motets" OR "morets") OR "lotes")).
• Removing quotes may allow a broader search: ((( motet or moret ) or mode ) or (( motets or morets ) or lotes )).
• Adding a wildcard symbol may retrieve word variants: ((("motet" or "moret") or "mode") or (("motets" or "morets") or "lotes"))*.
