• Performing a fuzzy search may retrieve terms with similar spellings: "(dann OR dank) ((meiner" OR ((deiner" OR (leiner" OR kleiner")) OR seiner")) OR seinen")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(dann OR dank) ((meiner\" OR ((deiner\" OR (leiner\" OR kleiner\")) OR seiner\")) OR seinen\")".
• Removing quotes may allow a broader search: (dann OR dank) ((meiner OR ((deiner OR (leiner OR kleiner )) OR seiner )) OR seinen ).
• Adding a wildcard symbol may retrieve word variants: "(dann OR dank) ((meiner" OR ((deiner" OR (leiner" OR kleiner")) OR seiner")) OR seinen")*.
