Perhaps you should try some spelling variations:
transport firms » transport fares, transport fuels, transport air
cash transfer » cash transfers
transfer 3 » transfer _, transfer 4, transfer a
act make » act maine, a make
out make » must make, just make, out case
guias do » guia do, guias de, guia de
firms a » firms _
3 do » _ do, 3 d, 1 do

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 ((act make) OR (out make)) transport firms a ) OR ( guias do cash transfer 3 do ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas ((act make) OR (out make)) transport firms a ) or ( guias do cash transfer 3 do ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas ((act make) OR (out make)) transport firms a ) or ( guias do cash transfer 3 do ))*.
