• If you are trying to use Boolean operators, they must be ALL CAPS: (wan OR lang) ((yang guang) OR (fan guon)) yu chen yan zhi ((rong yu) OR (rong su)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wan or lang) ((yang guang) or (fan guon)) yu chen yan zhi ((rong yu) OR (rong su)) ;*".
