• Performing a fuzzy search may retrieve terms with similar spellings: "(gerhard OR (((erhardt OR gerhardt) OR ebgebhardt) OR erhardt)) ((finckh" OR finkh") OR finck")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(gerhard OR (((erhardt OR gerhardt) OR ebgebhardt) OR erhardt)) ((finckh\" OR finkh\") OR finck\")*".
• Removing quotes may allow a broader search: (gerhard OR (((erhardt OR gerhardt) OR ebgebhardt) OR erhardt)) ((finckh OR finkh ) OR finck )*.
