• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan zhang) OR (han chang)) lei chen ((((yang jie) OR (ying jin))) OR (yang di)) dang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan zhang) OR (han chang)) lei chen ((((yang jie) or (ying jin))) or (yang di)) dang hai ;*".
