Perhaps you should try some spelling variations:
"motet" » "monet", "moret", "moet", "mottet", "modet", "movet"
"motets" » "monets", "morets", "moets", "mottets", "modets", "movets"
"lotet" » "loten"
"lotets" » "lotens", "lotes", "lotete"
"modet" » "modetn", "model", "mode"
"mote" » "motte", "mode", "move"

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