• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yanling) OR (yuan wang)) yang hui chen zheng xuan ((long des) OR (longum des)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yanling) or (yuan wang)) yang hui chen zheng xuan ((long des) OR (longum des)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yanling) or (yuan wang)) yang hui chen zheng xuan ((long des) OR (longum des)) ;*.
