Perhaps you should try some spelling variations:
transfer agent » transfer agents, transfer payment, transfer amount
transfer bei » transfer beim, transfers bei, transfer der
transfer de » transfer der, transfer fee, transfer key
luis rdf » luis f, luis de
luis c » luis f
c net » ic net, _ net, a net
heat » head

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 c net ((transfer de) OR (transfer bei)) acao ) OR ( luis rdf heat transfer agent _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis c net ((transfer de) OR (transfer bei)) acao ) or ( luis rdf heat transfer agent _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis c net ((transfer de) OR (transfer bei)) acao ) or ( luis rdf heat transfer agent _ ))*.
