• If you are trying to use Boolean operators, they must be ALL CAPS: zhang yan ((guan hui) OR (yuan hui)) rain yang tin ((zhong tai) OR (hong 7)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang yan ((guan hui) OR (yuan hui)) rain yang tin ((zhong tai) or (hong 7)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang yan ((guan hui) OR (yuan hui)) rain yang tin ((zhong tai) or (hong 7)) ;*.
