• If you are trying to use Boolean operators, they must be ALL CAPS: ((yuan wang) OR (yuan chang)) ((qian hu) OR (tan hua)) rein han min cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan wang) OR (yuan chang)) ((qian hu) or (tan hua)) rein han min cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan wang) OR (yuan chang)) ((qian hu) or (tan hua)) rein han min cong shu ;*.
