Perhaps you should try some spelling variations:
transport signal » transform signal, transport design, transport annual
sea transport » road transport, bus transport
transfers 3 » transfers _, transfer 3, transfer _
signal 6 » signals 6, signal _, signal 3
own sea » own ses, own seed, own real
3 basel » _ basel, 3 base, 4 basel
3 based » 3 base, d based, 19 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 signal 6 ) OR ( guias ((3 basel) OR (3 based)) transfers 3 case ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas own sea transport signal 6 ) or ( guias ((3 basel) OR (3 based)) transfers 3 case ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas own sea transport signal 6 ) or ( guias ((3 basel) OR (3 based)) transfers 3 case ))*.
