• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) OR (wang yang)) than china ren ((yang xi) or (((yang jin) or (yang jie)))) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) OR (wang yang)) than china ren ((yang xi) or (((yang jin) or (yang jie)))) cong shu ;*.
