Perhaps you should try some spelling variations:
transfer costs » transport costs, transfer amounts
data transfer » cash transfer, heat transfer
transfer der » transfer fees, transfer _
der carl » dr carl, de carl, der call
imf data » imf's data, dlf data
rdf data » dlf data
luis a » luis f, luis c

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 data transfer der carl ) OR ( luis ((imf data) OR (rdf data)) transfer costs _ ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis a data transfer der carl ) or ( luis ((imf data) or (rdf data)) transfer costs _ ))*.
