• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yan guan) OR (yang guang)) huang bin zhang i ((gong min) OR (cog min)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan guan) OR (yang guang)) huang bin zhang i ((gong min) or (cog min)) ;*".
