Perhaps you should try some spelling variations:
file transfer » wire transfer, risk transfer, food transfer
transfer der » transfer fees, transfer _
den transfer » gene transfer, heat transfer, data transfer
transfer bei » transfer beim, transfers bei, transfer fee
der across » der cross, debt across, eu across
sein file » sein die, sein eine
der den » oder den, der de, der der
bei den » bei der

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 sein file transfer der across ) OR ( basis der den transfer bei den ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis sein file transfer der across ) or ( basis der den transfer bei den ))*.
