green transport » urban transport, carbon transport
cost transform » cost transfer, cosine transform, cloud transform
gender a » gender _
1 green » 2 green, 4 green, 1 grenzen
luis 3 » luis f, luis c, luis a
3 cost » 3 costs, 2.3 cost, 3.3 cost
luis 1 » luis f, luis c, 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 3 cost transform gender a ) OR ( luis 1 green transport _ macao ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis 3 cost transform gender a ) or ( luis 1 green transport _ macao ))*.
