• If you are trying to use Boolean operators, they must be ALL CAPS: (wan OR wing) yang yang mu cheng zhang i ((song ming) OR (song bing)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wan or wing) yang yang mu cheng zhang i ((song ming) OR (song bing)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wan or wing) yang yang mu cheng zhang i ((song ming) OR (song bing)) ;*.
