Perhaps you should try some spelling variations:
transfer beim » transfer bei, transfers bei, transfer axiom
data transfer » heat transfer
cash transfer » cash transfers
den transfer » gene transfer, heat transfer, land transfer
beim carl » bei carl
luis rdf » luis f, luis de
luis a » luis f, luis c
a den » _ den, a der, a des

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