• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yan guan) OR (yang guang))) OR (fang yuan)) dr rene lang li ((wong siu) OR (hong yu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yan guan) OR (yang guang))) or (fang yuan)) dr rene lang li ((wong siu) or (hong yu)) ;*".
