• Performing a fuzzy search may retrieve terms with similar spellings: "(erhard OR (((erhardt OR gerhardt) OR ebgerhardt) OR erhardt)) (finckh" OR (finck" OR fink"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(erhard OR (((erhardt OR gerhardt) OR ebgerhardt) OR erhardt)) (finckh\" OR (finck\" OR fink\"))".
• Removing quotes may allow a broader search: (erhard OR (((erhardt OR gerhardt) OR ebgerhardt) OR erhardt)) (finckh OR (finck OR fink )).
• Adding a wildcard symbol may retrieve word variants: "(erhard OR (((erhardt OR gerhardt) OR ebgerhardt) OR erhardt)) (finckh" OR (finck" OR fink"))*.
