• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong cao) OR (dong bin)) tuan hua ren wang ((zhi tong) OR (hui tong)) shui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong cao) or (dong bin)) tuan hua ren wang ((zhi tong) OR (hui tong)) shui ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong cao) or (dong bin)) tuan hua ren wang ((zhi tong) OR (hui tong)) shui ;*.
