Perhaps you should try some spelling variations:
transport fuel » transport fares
den transport » de transport, sea transport, ion transport
sea transfer » heat transfer, net transfer, den transfer
a transfer » cash transfer, heat transfer, data transfer
areas co » areas coal, areas act, areas can
guias de » guia de, guide de, aguas de
co den » chao den, chor den
a o » a co

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