Perhaps you should try some spelling variations:
transfer costs » transport costs, transfer amounts
data transfer » cash transfer, heat transfer
land transfer » land transfers, land transport, funds transfer
den transfer » gene transfer, heat transfer, bank transfer
der carl » dr carl, de carl, der call
luis imf » luis f, luis m, luis i
imf data » imf's data, dlf data, rdf data
luis c » luis f

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 c ((den transfer) OR (land transfer)) der carl ) OR ( luis imf data transfer costs _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis c ((den transfer) OR (land transfer)) der carl ) or ( luis imf data transfer costs _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis c ((den transfer) OR (land transfer)) der carl ) or ( luis imf data transfer costs _ ))*.
