• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR lang) ((tan yang) OR (tan ying)) d huang ying jin ((zhong tai) OR (hong ng)) ;~.
• Adding a wildcard symbol may retrieve word variants: (wing or lang) ((tan yang) or (tan ying)) d huang ying jin ((zhong tai) or (hong ng)) ;*.
