• If you are trying to use Boolean operators, they must be ALL CAPS: wan qin zheng wei chen ((((((yang jie) OR (yang yi))) OR (yang xi))) OR (yang jui)) shang kai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan qin zheng wei chen ((((((yang jie) OR (yang yi))) or (yang xi))) or (yang jui)) shang kai ;*".
