• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yan pan) OR (((((yan clan) OR (das clan))) OR (yan yuan)))) yi yun song min tong shui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan pan) or (((((yan clan) OR (das clan))) or (yan yuan)))) yi yun song min tong shui ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((yan pan) or (((((yan clan) OR (das clan))) or (yan yuan)))) yi yun song min tong shui ;*.
