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