• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang OR wan) OR lang) yan ((yang yun) OR (yang yi)) cheng zhang hui zhong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang OR wan) or lang) yan ((yang yun) or (yang yi)) cheng zhang hui zhong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang OR wan) or lang) yan ((yang yun) or (yang yi)) cheng zhang hui zhong shu ;*.
