Perhaps you should try some spelling variations:
transfer relations » transfer operations, transfer stations, transfer simulations
data transfer » cash transfer, heat transfer
des transfer » des transfers, den transfer, der transfer
transfer bei » transfer beim, transfers bei, transfer der
relations a » relations _
bei martin » i martin
luis rdf » luis f, luis de
rdf data » dlf data, imf 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 bei martin ) OR ( luis rdf data transfer relations a ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis a des transfer bei martin ) or ( luis rdf data transfer relations a ))*.
