• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong ryangg) OR (wang yan)) rana hua rest ((yang yang) OR (wang yong)) long yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong ryangg) or (wang yan)) rana hua rest ((yang yang) OR (wang yong)) long yu ;".
• Adding a wildcard symbol may retrieve word variants: ((dong ryangg) or (wang yan)) rana hua rest ((yang yang) OR (wang yong)) long yu ;*.
