• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"politischen reden\") OR (\"politischen denkens\"))) or (\"politischen raum\"))".
• Removing quotes may allow a broader search: (((( politischen reden ) OR ( politischen denkens ))) or ( politischen raum )).
• Adding a wildcard symbol may retrieve word variants: (((("politischen reden") OR ("politischen denkens"))) or ("politischen raum"))*.
