• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (wang yanling))) OR (yuan cheng)) yang zili gene w thank kong (sar OR sara) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yang) OR (wang yanling))) or (yuan cheng)) yang zili gene w thank kong (sar or sara) ;*".
