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
transfer der » transfer fees, transfer _
der carl » dr carl, de carl, der call
luis imf » luis f, luis i
luis a » luis f, luis c
luis m » luisa m, luis f, luis c
a den » _ den, a der, a des

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