• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan yuan) OR (nan yan)) jing yul chen dong liu ((dong sin) OR (young yun)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan yuan) OR (nan yan)) jing yul chen dong liu ((dong sin) or (young yun)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan yuan) OR (nan yan)) jing yul chen dong liu ((dong sin) or (young yun)) ;*.
