Perhaps you should try some spelling variations:
transfer system » transfer systems, transport system, transit system
data transfer » cash transfer, heat transfer
transfers bei » transfer bei, transfer beim, transfers ai
system cas » system case, system can, systems case
bei recht » bei nicht, dem recht, b recht
aguas de » aguas del, aguas do, vagues de
del der » del lider, del poder, ziel der
de data » e data, wide data, de datos

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: (( aguas ((del der) OR (del de)) transfers bei recht ) OR ( aguas de data transfer system cas ))~.
• Adding a wildcard symbol may retrieve word variants: (( aguas ((del der) or (del de)) transfers bei recht ) or ( aguas de data transfer system cas ))*.
