Perhaps you should try some spelling variations:
transfer agents » transfer payments, transfer amounts, transfer payment
data transfer » cash transfer, heat transfer
des transfers » net transfers, cash transfers, arms transfers
transfers ai » transfers i, transfers bei, transfers dau
luis rdf » luis f, luis de
rdf data » dlf data, imf data
ai carl » bei carl, iii carl, aus carl
luis 2 » luis f, luis c, luis e
luis a » luis f, luis c

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 2) OR (luis a)) des transfers ai carl ) OR ( luis rdf data transfer agents _ ))~.
• Adding a wildcard symbol may retrieve word variants: (( ((luis 2) or (luis a)) des transfers ai carl ) or ( luis rdf data transfer agents _ ))*.
