Perhaps you should try some spelling variations:
transport fuel » transport fares
sea transport » road transport, bus transport
transfer 4 » transfer _, transfer a, transfer der
transfer 3 » transfer _, transfer a, transfer 3.2
areas co » areas coal, areas act, areas can
aguas de » aguas del, aguas do, vagues de
de based » dge based, de base, de bases
co sea » co se, cows sea
fuel a » fuel _, fuel tax, fuel gas

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: (( areas co sea transport fuel a ) OR ( aguas de based ((transfer 4) OR (transfer 3)) ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas co sea transport fuel a ) or ( aguas de based ((transfer 4) OR (transfer 3)) ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas co sea transport fuel a ) or ( aguas de based ((transfer 4) OR (transfer 3)) ao ))*.
