Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
a transformed » _ transformed, _ transformer, a transforming
transformed 1 » transformed _, transformer 1, transformed a
schemes vss » schemes das, schemes use, schemes versus
langue we » langue de, langues de, lange weg
code den » code de, code des, code oder
code der » code oder, codes der, code de
we a » web a, owe a, we _
acao » cacao, macao, cao

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: (( vue ((code den) OR (code der)) transfer schemes vss ) OR ( langue we a transformed 1 acao ))~.
• Adding a wildcard symbol may retrieve word variants: (( vue ((code den) or (code der)) transfer schemes vss ) or ( langue we a transformed 1 acao ))*.
