• If you are trying to use Boolean operators, they must be ALL CAPS: yi chang ((((yan fan) OR (yan guan))) OR (yang dean)) cost sharing our kong (sar OR saur) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yi chang ((((yan fan) OR (yan guan))) or (yang dean)) cost sharing our kong (sar or saur) ;*".
