transport fuel » transport fares
transfers em » transfers im, transfers bei, transfers ein
fuel acao » fuel co
luis de » luis e
de cash » de cas, do cash, de caso

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias _ ocean transport fuel acao ) OR ( luis de cash transfers em (cacao OR cmacao) ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias _ ocean transport fuel acao ) OR ( luis de cash transfers em (cacao OR cmacao) ))*.
