• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan ting) or (huang ting)) jia chung kang chan ming ((hong shu) OR (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan ting) or (huang ting)) jia chung kang chan ming ((hong shu) OR (cong shu)) ;*.
