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

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