Perhaps you should try some spelling variations:
green transport » urban transport, carbon transport
loss transfer » mass transfer, cost transfer, load transfer
transfer file » transfer fee, transfer from, transfer fees
luis 3 » luis c, luis a, luis e
file a » file _, file 1, file 2
luis 2 » luis c, luis a, luis e

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis 3 loss transfer file a ) OR ( ((luis 2) OR (luis f)) green transport _ macao ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis 3 loss transfer file a ) OR ( ((luis 2) OR (luis f)) green transport _ macao ))*.
