Perhaps you should try some spelling variations:
transfer costs » transport costs, transfer amounts
data transfer » cash transfer, heat transfer
transfer der » transfer fees, transfer _
transfer dr » transfer _, transfer 3, transfer 4
luis a » luis f
luis c » luis f
c data » 1 data, lcc data
a das » 1 das, 2 das, 3 das

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