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

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