• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong ((((yan guan) OR (gan guan))) OR (yang jun)) gain yang zhao zheng (hai OR hadi) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((((yan guan) OR (gan guan))) or (yang jun)) gain yang zhao zheng (hai or hadi) ;".
• Adding a wildcard symbol may retrieve word variants: wang yong ((((yan guan) OR (gan guan))) or (yang jun)) gain yang zhao zheng (hai or hadi) ;*.
