• If you are trying to use Boolean operators, they must be ALL CAPS: tang zheng quan yi ((chen chang) OR (shen chang)) wang ((yong yu) OR (young yun)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tang zheng quan yi ((chen chang) or (shen chang)) wang ((yong yu) OR (young yun)) ;~".
• Adding a wildcard symbol may retrieve word variants: tang zheng quan yi ((chen chang) or (shen chang)) wang ((yong yu) OR (young yun)) ;*.
