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, a transfer
areas coal » areas can
transfer a » transfer _, transfer 3, transfer 4
areas co » areas act, areas can, areas _
guias de » guia de, guide de, aguas de
de sea » de ses, de ser
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) OR (areas coal)) den transport fuel _ ) OR ( guias de sea transfer a o ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((areas co) OR (areas coal)) den transport fuel _ ) or ( guias de sea transfer a o ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((areas co) OR (areas coal)) den transport fuel _ ) or ( guias de sea transfer a o ))*.
