• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((kyoung yun) OR (young yun)) ((tan kai) OR (tan ah)) yang du gong kai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((kyoung yun) OR (young yun)) ((tan kai) or (tan ah)) yang du gong kai ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((kyoung yun) OR (young yun)) ((tan kai) or (tan ah)) yang du gong kai ;*.
