Perhaps you should try some spelling variations:
transfer costs » transport costs, transfer amounts
transfer fees » transfer from
et transfer » net transfer, ee transfer, heat transfer
fees carl » des carl
imf data » imf's data, dlf data
rdf data » dlf data
f et » fr et, _ et, f e

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 f et transfer fees carl ) OR ( luis ((imf data) OR (rdf data)) transfer costs _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis f et transfer fees carl ) or ( luis ((imf data) OR (rdf data)) transfer costs _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis f et transfer fees carl ) or ( luis ((imf data) OR (rdf data)) transfer costs _ ))*.
