Perhaps you should try some spelling variations:
transport design » transport decisions, transport demand
sea transport » road transport, bus transport
transfers 6 » transfers 3, transfers 2, transfers 7
own sea » own ses, own seed, own real
guias 3 » guias de
3 based » 3 base, 3 basel, d based
aguas » agus, agua

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 own sea transport design 4 ) OR ( guias 3 based ((transfers 6) OR (transfers _)) cas ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas own sea transport design 4 ) or ( guias 3 based ((transfers 6) OR (transfers _)) cas ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas own sea transport design 4 ) or ( guias 3 based ((transfers 6) OR (transfers _)) cas ))*.
