Perhaps you should try some spelling variations:
transfer costs » transfer amounts
gene transfer » wire transfer, heat transfer, file transfer
transfer der » transfer fees, transfer _
der carl » dr carl, de carl, der call
luis rdf » luis de
rdf data » dlf data, imf data
f gene » _ gene, a gene, e gene

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