Perhaps you should try some spelling variations:
transfer costs » transport costs, transfer amounts
datos transfer » data transfer, data transfers, mass transfer
transfer bei » transfer beim, transfers bei, transfer der
bei martha » bei martin, bei hertha, bei maria
costs case » costs cash
1 datos » a datos, b datos, c datos
luis 1 » luis f, luis c, luis a
a gas » 2 gas, 3 gas, a gay

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) OR (_ gas)) transfer bei martha ) OR ( luis 1 datos transfer costs case ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis ((a gas) or (_ gas)) transfer bei martha ) or ( luis 1 datos transfer costs case ))*.
