• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((xuan fang) OR (yuan wang))) OR (xia fang)) ((ii china) OR (1 china)) zhang can hong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((xuan fang) OR (yuan wang))) or (xia fang)) ((ii china) or (1 china)) zhang can hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((xuan fang) OR (yuan wang))) or (xia fang)) ((ii china) or (1 china)) zhang can hong shu ;*.
