Perhaps you should try some spelling variations:
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 » der abda, les 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) OR (der acta)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua _ der transfer schemes one ) or ( agua et la transformation ((der acao) OR (der acta)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( agua _ der transfer schemes one ) or ( agua et la transformation ((der acao) OR (der acta)) ))*.
