• Performing a fuzzy search may retrieve terms with similar spellings: "(dan OR main) (((heiner" OR (deine" OR eine")) OR heiner") OR ((seiner" OR einer") OR seine"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(dan OR main) (((heiner\" OR (deine\" OR eine\")) OR heiner\") OR ((seiner\" OR einer\") OR seine\"))".
• Removing quotes may allow a broader search: (dan OR main) (((heiner OR (deine OR eine )) OR heiner ) OR ((seiner OR einer ) OR seine )).
• Adding a wildcard symbol may retrieve word variants: "(dan OR main) (((heiner" OR (deine" OR eine")) OR heiner") OR ((seiner" OR einer") OR seine"))*.
