• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang wang) OR (yang yang))) OR (yang guang)) yan hua yi yang ((jie cong) OR (jie song)) shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang wang) or (yang yang))) or (yang guang)) yan hua yi yang ((jie cong) OR (jie song)) shu ;*".
