Perhaps you should try some spelling variations:
"motet" » "monet", "moret", "moet", "mottet", "modet", "movet"
"motets" » "monets", "morets", "moets", "mottets", "modets", "movets"
"lotet" » "loten"
"mote" » "motte", "mode", "move"
"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 ("mote" OR "more")) OR ("motets" OR "lotes")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"motet\" OR \"lotet\") or (\"mote\" or \"more\")) or (\"motets\" or \"lotes\"))".
• Removing quotes may allow a broader search: ((( motet OR lotet ) or ( mote or more )) or ( motets or lotes )).
• Adding a wildcard symbol may retrieve word variants: ((("motet" OR "lotet") or ("mote" or "more")) or ("motets" or "lotes"))*.
