Perhaps you should try some spelling variations:
transformation der » transformation _
la transformation » a transformation, data transformation, die transformation
transfer schemes » transfer scheme, transfer systems
der transfer » der transfers, den transfer, peer transfer
schemes one » schemes some, schema one, schemes use
der acao » de acao, der aal, der acta
agua et » agua e

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: (( agua _ der transfer schemes one ) OR ( agua et la transformation der acao ))~.
• Adding a wildcard symbol may retrieve word variants: (( agua _ der transfer schemes one ) or ( agua et la transformation der acao ))*.
