Perhaps you should try some spelling variations:
transfer amount » transfer amounts
datos transfer » data transfer, data transfers, mass transfer
des transfer » des transfers, den transfer, der transfer
amount based » account based, accounts based, agent based
e datos » de datos, 1 datos, a datos
luis e » luis a

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) OR (luis f)) des transfer _ maria ) OR ( luis e datos transfer amount based ))~.
• Adding a wildcard symbol may retrieve word variants: (( ((luis c) or (luis f)) des transfer _ maria ) or ( luis e datos transfer amount based ))*.
