Perhaps you should try some spelling variations:
transfer cities » transform cities, transfer crisis, transfer facilities
des transfer » des transfers, den transfer, der transfer
transfer der » transfer fees, transfer _
der carl » dr carl, de carl, der call
dlf data » rdf data
imf data » imf's data, rdf data
luis a » luis f, luis c
a des » a der, a 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 a des transfer der carl ) OR ( luis ((dlf data) OR (imf data)) transfer cities _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis a des transfer der carl ) or ( luis ((dlf data) OR (imf data)) transfer cities _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis a des transfer der carl ) or ( luis ((dlf data) OR (imf data)) transfer cities _ ))*.
