Perhaps you should try some spelling variations:
data transfer » cash transfer, heat transfer
der transfer » der transfers, den transfer, peer transfer
transfer bei » transfer beim, transfers bei, transfer der
bei marc » bei marx, bei maria, bei carl
luis rdf » luis de
rdf data » dlf data, imf data
f der » _ der, 2 der, 3 der
builders » builds, bilder

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 der transfer bei marc ) OR ( luis rdf data transfer ((builder 4) OR (builders _)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis f der transfer bei marc ) or ( luis rdf data transfer ((builder 4) OR (builders _)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis f der transfer bei marc ) or ( luis rdf data transfer ((builder 4) OR (builders _)) ))*.
