Perhaps you should try some spelling variations:
road transit » road transition, road transport, rapid transit
transfers 2 » transfers _, transfers 3, transfers 6
aguas air » areas air
air road » air raid
3 based » 3 basel, d based, 19 based
3 base » 3 basel, _ base, a base
2 ao » 2 a, 2 co, 2 do
times » time

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 air road transit times _ ) OR ( guias ((3 based) OR (3 base)) transfers 2 ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas air road transit times _ ) or ( guias ((3 based) OR (3 base)) transfers 2 ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas air road transit times _ ) or ( guias ((3 based) OR (3 base)) transfers 2 ao ))*.
