Perhaps you should try some spelling variations:
transfers field » transfers united
der transfer » der transfers, den transfer, peer transfer
transfer bei » transfer beim, transfers bei, transfer der
field case » field based
bei mark » bei marx, bei marc, bei maria
dlf data » rdf data
imf data » imf's data, rdf data
luis 2 » luis f, luis c, luis a
2 der » _ 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 2 der transfer bei mark ) OR ( luis ((dlf data) OR (imf data)) transfers field case ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis 2 der transfer bei mark ) or ( luis ((dlf data) OR (imf data)) transfers field case ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis 2 der transfer bei mark ) or ( luis ((dlf data) OR (imf data)) transfers field case ))*.
