• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan yang juden ((im papier) OR (ein papier)) david ((hong hai) or (young cho)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan yang juden ((im papier) OR (ein papier)) david ((hong hai) or (young cho)) ;*.
