• If you are trying to use Boolean operators, they must be ALL CAPS: ((((huang yang) OR (zong cheng))) OR (wang ning)) yang jie yu fang ((a cong) OR (a cone)) shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((huang yang) or (zong cheng))) or (wang ning)) yang jie yu fang ((a cong) OR (a cone)) shu ;*".
