Perhaps you should try some spelling variations:
"motet" » "lotet", "monet", "moret", "mottet", "modet"
"motets" » "lotets", "monets", "morets", "mottets", "modets"
"mote" » "motte", "more", "mode"
"lotes" » "notes", "votes", "lopes"
"lottes" » "flottes", "gottes", "lotte"

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