• The words AND, OR and NOT may confuse the search; try adding quotes: "eigenverlag heinrich schmidt und walter ((stahl OR (stall OR (stoll OR soll))) OR strahle)~".
• Adding a wildcard symbol may retrieve word variants: eigenverlag heinrich schmidt und walter ((stahl OR (stall OR (stoll OR soll))) OR strahle)*.
