Perhaps you should try some spelling variations:
transfer costs » transport costs, transfer amounts
data transfer » cash transfer, heat transfer
transfer dr » transfer der, transfer _, transfer 3
dr carl » dr karl
luis c » luis f
c data » 1 data, lcc data
a das » 1 das, 3 das, _ das
2 das » 1 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) OR (2 das)) transfer dr carl ) OR ( luis c data transfer costs _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis ((a das) OR (2 das)) transfer dr carl ) or ( luis c data transfer costs _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis ((a das) OR (2 das)) transfer dr carl ) or ( luis c data transfer costs _ ))*.
