Perhaps you should try some spelling variations:
safe transport » sea transport, free transport, de transport
transport fuel » transport fares
transfers 2.2 » transfers 1.2, transfers 3.2, transfers 2.1
transfer 2.2 » transfer 3.2, transfer _, transfer der
areas two » areas co
two safe » two safety, two stage, two state
guias do » guia do, guias de, guia de
fuel a » fuel _, fuel tax, fuel gas
cash » case

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: (( areas two safe transport fuel a ) OR ( guias do cash ((transfers 2.2) OR (transfer 2.2)) co ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas two safe transport fuel a ) or ( guias do cash ((transfers 2.2) OR (transfer 2.2)) co ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas two safe transport fuel a ) or ( guias do cash ((transfers 2.2) OR (transfer 2.2)) co ))*.
