Perhaps you should try some spelling variations:
transports signal » transform signal, transports regional
des transports » bus transport, gas transport
basel transfer » based transfer, based transfers, basin transfer
transfer 3 » transfer _, transfer 4, transfer a
signal 6 » signals 6, signal _, signal 3
own des » own ses, own ideas, own best
guias 3 » guias de
3 basel » _ basel, 3 base, 3 based
aguas » agus, agua

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas own des transports signal 6 ) OR ( guias 3 basel transfer 3 case ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas own des transports signal 6 ) OR ( guias 3 basel transfer 3 case ))*.
