• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((yanling data) OR (banking data)) german gender talk min ((hong g) or (hong ng)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((yanling data) OR (banking data)) german gender talk min ((hong g) or (hong ng)) ;*.
