das transfer » gas transfer, cash transfer, data transfer
transfer 3 » transfer _, transfer 4, transfer a
areas can » areas case, areas cash, areas coal

guias f » guias de
f das » 1 das, 2 das, 3 das
3 ao » 3 a, 3 co, 3 do

• If you are trying to use Boolean operators, they must be ALL CAPS: (( areas can ideas ((transform cote) OR (transform tvdft)) _ ) OR ( guias f das transfer 3 ao ))~.
• Adding a wildcard symbol may retrieve word variants: (( areas can ideas ((transform cote) or (transform tvdft)) _ ) or ( guias f das transfer 3 ao ))*.
