• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((doring christian) OR (von christian)) (nach\" OR buch\")~".
• Removing quotes may allow a broader search: ((doring christian) OR (von christian)) (nach OR buch )~.
• Adding a wildcard symbol may retrieve word variants: "((doring christian) OR (von christian)) (nach" OR buch")*.
