• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((((yan yuan) OR (nan yan))) OR (yan guan)) hua chen zhen min wong shiu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((((yan yuan) OR (nan yan))) or (yan guan)) hua chen zhen min wong shiu ;".
