• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((((yuan lin) OR (yuan li))) OR (wang qin)) ((kim jang) OR (kim kwang)) min congo shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((((yuan lin) or (yuan li))) or (wang qin)) ((kim jang) OR (kim kwang)) min congo shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((((yuan lin) or (yuan li))) or (wang qin)) ((kim jang) OR (kim kwang)) min congo shu ;*.
