Perhaps you should try some spelling variations:
"motet" » "motets", "monet", "moret", "modet", "movet"
"mote" » "more", "mode", "move"
"motes" » "mores", "modes", "moves", "motets", "notes"
"mottet" » "mottets", "mouttet", "cottet", "mittet"
"motte" » "mitte"
"mottes" » "mittes", "mottoes", "mottets", "mottles"
"lotet" » "loten"

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