make transport » smoke transport, safe transport, care transport
cas transfers » cash transfers, cash transfer's, cash transfer
transfers 3 » transfers _, transfer 3, transfer _
areas can » areas case, areas cash, areas coal
guias de » guide de, aguas de, guia do
firms a » firms _
3 ao » 3 a, 3 co, 3 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 can make transport firms a ) OR ( ((guias de) OR (guia de)) cas transfers 3 ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas can make transport firms a ) or ( ((guias de) OR (guia de)) cas transfers 3 ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas can make transport firms a ) or ( ((guias de) OR (guia de)) cas transfers 3 ao ))*.
