Perhaps you should try some spelling variations:
marine transport » maritime transport, carbon transport
transform a » transform _, transform our, transform 2.4
en marine » sea marine, non marine, _ marine
new index » new india
a acao » a adocao
guia » gua, gui, gaia
guias » guas, guis, gaias

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: (( guia en marine transport sector a ) OR ( guias ((new index) OR (law index)) transform a acao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guia en marine transport sector a ) or ( guias ((new index) OR (law index)) transform a acao ))~".
• Adding a wildcard symbol may retrieve word variants: (( guia en marine transport sector a ) or ( guias ((new index) OR (law index)) transform a acao ))*.
