Perhaps you should try some spelling variations:
"motet" » "lotet", "mote", "monet"
"motets" » "lotets", "motes", "monets"
"lotets" » "lotet", "lotens", "lotete"
"motes" » "notes", "modes", "moves"
"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 (((("motets" OR "lotets") OR "motes") OR "motes") OR ("lotes" OR "lottes"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"motet\" or ((((\"motets\" OR \"lotets\") or \"motes\") or \"motes\") or (\"lotes\" or \"lottes\")))".
• Removing quotes may allow a broader search: ( motet or (((( motets OR lotets ) or motes ) or motes ) or ( lotes or lottes ))).
• Adding a wildcard symbol may retrieve word variants: ("motet" or (((("motets" OR "lotets") or "motes") or "motes") or ("lotes" or "lottes")))*.
