Perhaps you should try some spelling variations:
transfer agent » transfer agents, transfer payment, transfer amount
transfers have » transfers made
des transfers » net transfers, cash transfers, arms transfers
agent a » agents a, agent _, agent 4
luis a » luis f, luis c
f data » 2 data, dlf data, imf data
1 data » 2.1 data, 3.1 data, 4.1 data
a des » a der, a das
macao » macro, macau, cacao

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 have macao ) OR ( luis ((f data) OR (1 data)) transfer agent a ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis a des transfers have macao ) or ( luis ((f data) or (1 data)) transfer agent a ))*.
