Perhaps you should try some spelling variations:
transfer agent » transfer agents, transfer payment, transfer amount
des transfers » net transfers, cash transfers, arms transfers
transfers bei » transfer bei, transfer beim, transfers ai
bei martha » bei martin, bei hertha, bei maria
dlf data » imf data, rdf data
luis c » luis f
1 data » 2.1 data, 3.1 data, 4.1 data
c des » c does, c der, c das

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 des transfers bei martha ) OR ( luis ((dlf data) OR (1 data)) transfer agent _ ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis c des transfers bei martha ) or ( luis ((dlf data) or (1 data)) transfer agent _ ))*.
