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