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