Perhaps you should try some spelling variations:
transport signal » transform signal, transport design, transport annual
land transfers » funds transfers, cash transfers, food transfers
land transport » road transport
signal _ » signals _
own bus » own boss, own best, own buzz
guias 3 » guias de
b case » tb case, 2 case, 1 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 bus transport signal _ ) OR ( guias 3 ((land transfers) OR (land transport)) b case ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agus own bus transport signal _ ) or ( guias 3 ((land transfers) OR (land transport)) b case ))~".
• Adding a wildcard symbol may retrieve word variants: (( agus own bus transport signal _ ) or ( guias 3 ((land transfers) OR (land transport)) b case ))*.
