Perhaps you should try some spelling variations:
transfer agents » transfer payments, transfer amounts, transfer payment
des transfers » net transfers, cash transfers, arms transfers
data transfer » cash transfer, heat transfer
agents 5 » agents _, agents 3, agents 8
_ macao » _ macro
luis a » luis f
luis c » luis f
c data » 1 data, lcc data
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 transfers ((ai macao) OR (_ macao)) ) OR ( luis c data transfer agents 5 ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis a des transfers ((ai macao) OR (_ macao)) ) or ( luis c data transfer agents 5 ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis a des transfers ((ai macao) OR (_ macao)) ) or ( luis c data transfer agents 5 ))*.
