Perhaps you should try some spelling variations:
"motet" » "mote", "moret", "moet"
"motets" » "motes", "morets", "moets"
"lotet" » "loten"
"monet" » "monnet", "moneta", "monete"
"motte" » "mitte"
"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 "lotet") OR "monet") OR "motte") OR ("motets" OR "lotes")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"motet\" OR \"lotet\") or \"monet\") or \"motte\") or (\"motets\" or \"lotes\"))".
• Removing quotes may allow a broader search: (((( motet OR lotet ) or monet ) or motte ) or ( motets or lotes )).
• Adding a wildcard symbol may retrieve word variants: (((("motet" OR "lotet") or "monet") or "motte") or ("motets" or "lotes"))*.
