Perhaps you should try some spelling variations:
data transfers » data transfer, water transfers, cash transfers
net transfer » net transfers, heat transfer, money transfer
transfer bei » transfer beim, transfers bei, transfer der
bei martha » bei martin, bei hertha, bei maria
luis 2.1 » ellis 2.1, eucs 2.1, luis h.b
luis c » luis f
c net » ic net, _ net, a net
ein a » ein _, win a, min a

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 c net transfer bei martha ) OR ( luis 2.1 data transfers ((ein a) OR (ein am)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis c net transfer bei martha ) or ( luis 2.1 data transfers ((ein a) OR (ein am)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis c net transfer bei martha ) or ( luis 2.1 data transfers ((ein a) OR (ein am)) ))*.
