data transfer » cash transfer, heat transfer
der transfers » des transfers, net transfers, die transfers
transfer test » transfer west, transform test, transfer cost
der transfer » den transfer, peer transfer, far transfer
luis dlf » luis f, luis de
dlf data » imf data, rdf data
dr carl » dr karl
luis c » luis f

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 ((der transfer) OR (der transfers)) dr carl ) OR ( luis dlf data transfer test _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis c ((der transfer) OR (der transfers)) dr carl ) or ( luis dlf data transfer test _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis c ((der transfer) OR (der transfers)) dr carl ) or ( luis dlf data transfer test _ ))*.
