• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yang) OR (yang yang)) chin chen chuan hua ((zhong zhi) OR (hong tan)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) OR (yang yang)) chin chen chuan hua ((zhong zhi) or (hong tan)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yang) OR (yang yang)) chin chen chuan hua ((zhong zhi) or (hong tan)) ;*.
