Perhaps you should try some spelling variations:
transfer costs » transport costs, transfer amounts
data transfer » cash transfer, heat transfer
tariffs marc » tariffs a, tariffs data
costs can » costs case, costs cash, costs chap
luis a » luis f, luis c
2 set » _ set
a set » _ set

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 ((2 set) OR (a set)) transport tariffs marc ) OR ( luis a data transfer costs can ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis ((2 set) OR (a set)) transport tariffs marc ) or ( luis a data transfer costs can ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis ((2 set) OR (a set)) transport tariffs marc ) or ( luis a data transfer costs can ))*.
