• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan wang) OR (((chan ming) OR (chan kang)))) yang yi gene chang a ((hong gang) OR (gong gang)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) or (((chan ming) or (chan kang)))) yang yi gene chang a ((hong gang) OR (gong gang)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan wang) or (((chan ming) or (chan kang)))) yang yi gene chang a ((hong gang) OR (gong gang)) ;*.
