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