• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang tan hua gene ((((yang jie) OR (((yang xi) OR (yang yi))))) OR (yang di)) won sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang tan hua gene ((((yang jie) or (((yang xi) OR (yang yi))))) or (yang di)) won sau ;*".
