• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis ((rene a) OR (rene l)) transforming cities across ) or ( luis a den transfer der cap ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis ((rene a) OR (rene l)) transforming cities across ) or ( luis a den transfer der cap ))*.
