• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang zhang si cheng zhang ((((dai cong) OR (bai chong))) OR (yan cong)) shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang zhang si cheng zhang ((((dai cong) OR (bai chong))) or (yan cong)) shu ;*".
