Perhaps you should try some spelling variations:
state transport » safe transport, space transport, solute transport
transport fuel » transport fares
areas two » areas co
two state » two stage, edo state
guias de » guia de, guide de, aguas de
3.2 cost » 5.2 cost, 3.2 case, 3.2 core
de cash » de cas, do cash, de caso
fuel a » fuel _, fuel tax, fuel gas
3.2 co » 3.2 core, 3.2 code

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 state transport fuel a ) OR ( guias de cash transfers ((3.2 co) OR (3.2 cost)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas two state transport fuel a ) or ( guias de cash transfers ((3.2 co) OR (3.2 cost)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas two state transport fuel a ) or ( guias de cash transfers ((3.2 co) OR (3.2 cost)) ))*.
