• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan han hua gain ((((yang lin) OR (yan liang))) OR (yang jin)) dang (hai OR haji) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan han hua gain ((((yang lin) or (yan liang))) or (yang jin)) dang (hai OR haji) ;*".
