• The words AND, OR and NOT may confuse the search; try adding quotes: "dong tin tan china ren ying john ((((wong siu) or (((wong sam) OR (wong sau))))) or (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong tin tan china ren ying john ((((wong siu) or (((wong sam) OR (wong sau))))) or (cong shu)) ;*.
