• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong ceos) OR (dong cao)) say chuan daun tang min ((hong ng) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong ceos) OR (dong cao)) say chuan daun tang min ((hong ng) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong ceos) OR (dong cao)) say chuan daun tang min ((hong ng) or (zhong zhi)) ;*.
