• If you are trying to use Boolean operators, they must be ALL CAPS: zhang ping wang li yun ((young jean) OR (young eun)) ((song siu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang ping wang li yun ((young jean) OR (young eun)) ((song siu) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang ping wang li yun ((young jean) OR (young eun)) ((song siu) or (wong siu)) ;*.
