• If you are trying to use Boolean operators, they must be ALL CAPS: yan wang ((bang hong) OR (wang hong)) ((chen zheng) OR (chen zhen)) min hyoung seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yan wang ((bang hong) or (wang hong)) ((chen zheng) OR (chen zhen)) min hyoung seo ;~".
• Adding a wildcard symbol may retrieve word variants: yan wang ((bang hong) or (wang hong)) ((chen zheng) OR (chen zhen)) min hyoung seo ;*.
