Perhaps you should try some spelling variations:
transfer costs » transport costs, transfer amounts
data transfer » cash transfer, heat transfer
transfer bei » transfer beim, transfers bei, transfer der
costs case » costs cash
bei marc » bei marx, bei maria, bei carl
luis dlf » luis f, luis de
dlf data » imf data, rdf data

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: (( luis ((a cash) OR (a case)) transfer bei marc ) OR ( luis dlf data transfer costs case ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis ((a cash) or (a case)) transfer bei marc ) or ( luis dlf data transfer costs case ))*.
