• If you are trying to use Boolean operators, they must be ALL CAPS: zhang yan ((((((yang jie) OR (yang xi))) OR (yang yi))) OR (yang di)) china long tan hong chun ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang yan ((((((yang jie) OR (yang xi))) or (yang yi))) or (yang di)) china long tan hong chun ;*".
