Perhaps you should try some spelling variations:
transport based » transport asset, transport burden, transport travel
sea transport » road transport, bus transport
base transfer » based transfer, based transfers, basin transfer
areas coal » areas can
areas co » areas act, areas can, areas _
guias de » guia de, guide de, aguas de
based a » based ai, based ad, based na

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