• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((guang wang) OR (huang yang)) yue chen dong xu ((dong sin) or (young young)) ;~".
• Adding a wildcard symbol may retrieve word variants: yang ((guang wang) OR (huang yang)) yue chen dong xu ((dong sin) or (young young)) ;*.
