Perhaps you should try some spelling variations:
transport signal » transform signal, transport design, transport annual
sea transport » road transport, bus transport
base transfer » based transfer, based transfers, basin transfer
transfer 6 » transfer _, transfer 3, transfer 4
signal _ » signals _
own sea » own ses, own seed, own real
guias 3 » guias de
3 base » 3 based, 3 basel, _ base
6 case » 2 case
agus » angus, aus, ages

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: (( agus own sea transport signal _ ) OR ( guias 3 base transfer 6 case ))~.
• Adding a wildcard symbol may retrieve word variants: (( agus own sea transport signal _ ) or ( guias 3 base transfer 6 case ))*.
