Perhaps you should try some spelling variations:
new transfers » net transfers, des transfers, eu transfers
der transfers » des transfers, der transfer, net transfers
data transfer » cash transfer, heat transfer
transfer tax » transfer taxes, transfer _
avi maria » vi maria, david maria, davis maria
luis rdf » luis f, luis de
rdf data » dlf data, imf data
luis a » luis f, luis c

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 a ((new transfers) OR (der transfers)) avi maria ) OR ( luis rdf data transfer tax _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis a ((new transfers) OR (der transfers)) avi maria ) or ( luis rdf data transfer tax _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis a ((new transfers) OR (der transfers)) avi maria ) or ( luis rdf data transfer tax _ ))*.
