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