Perhaps you should try some spelling variations:
transition times » transition time, transitional times, transition regimes
road transition » rapid transition, rural transition, 2d transition
transfers 2 » transfers _, transfers 3, transfers 6
aguas air » areas air
air road » air raid
3 basel » _ basel, 3 based, 4 basel
3 base » 3 based, _ base, a base
2 co » _ co, a co, 2 c

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 transition times _ ) OR ( guias ((3 base) OR (3 basel)) transfers 2 co ))~.
• Adding a wildcard symbol may retrieve word variants: (( aguas air road transition times _ ) or ( guias ((3 base) or (3 basel)) transfers 2 co ))*.
