• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((((yan lin) OR (yan liang))) OR (((yang jie) OR (yang jin)))) li gong min tong shui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((((yan lin) OR (yan liang))) or (((yang jie) or (yang jin)))) li gong min tong shui ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((((yan lin) OR (yan liang))) or (((yang jie) or (yang jin)))) li gong min tong shui ;*.
