Perhaps you should try some spelling variations:
roles transport » role transport, nodes transport, release transport
transport fares » transport access
cas transfer's » cash transfer's, cash transfers, cash transfer
transfer's 1 » transfer 1, transfers 1.2, transfers 1.3
areas main » areas marine, areas air, areas can
main roles » main role, chain roles, main routes
guias de » guia de, aguas de, guia do
guide de » guide _, guide a, guide 1
fares _ » fires _, shares _
1 do » _ 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 main roles transport fares _ ) OR ( ((guias de) OR (guide de)) cas transfer's 1 do ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas main roles transport fares _ ) or ( ((guias de) OR (guide de)) cas transfer's 1 do ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas main roles transport fares _ ) or ( ((guias de) OR (guide de)) cas transfer's 1 do ))*.
