Perhaps you should try some spelling variations:
green transport » urban transport, carbon transport
al transformed » a transformed, has transformed, law transformed
transport can » transport a, transport cost, transport data
transformed 1 » transformed _, transformer 1, transformed a
aguas a.l » aguas del
a.l green » a green, 2.1 green, 3.2 green
can cross » can close, can cost
agua et » agua e
1 cao » 1 can, 1 ao, _ cao

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: (( aguas a.l green transport can cross ) OR ( agua et al transformed 1 cao ))~.
• Adding a wildcard symbol may retrieve word variants: (( aguas a.l green transport can cross ) or ( agua et al transformed 1 cao ))*.
