• If you are trying to use Boolean operators, they must be ALL CAPS: ((huang chang) OR (huang jing)) can china n gain john ((kong siu) OR (kong eiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((huang chang) or (huang jing)) can china n gain john ((kong siu) OR (kong eiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((huang chang) or (huang jing)) can china n gain john ((kong siu) OR (kong eiu)) ;*.
