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