Perhaps you should try some spelling variations:
fuel transport » rural transport, rail transport, bus transport
based transfer » based transfers, basin transfer, basin transfers
sel transport » sea transport, real transport, salt transport
guias des » guias de, guia de, bias des
des based » aes based, ses based, codes based
aguas do » aguas de, aguas del
sft 3 » set 3, sft a, smt 3

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: (( aguas do ((sel transport) OR (fuel transport)) sft 3 ) OR ( guias des based transfer _ co ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas do ((sel transport) OR (fuel transport)) sft 3 ) or ( guias des based transfer _ co ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas do ((sel transport) OR (fuel transport)) sft 3 ) or ( guias des based transfer _ co ))*.
