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