• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((bernhard OR erhard) OR ((gerhardt OR gerhardtt) OR ggerhard)) ((finckh\" OR finck\") OR fink\")~".
• Removing quotes may allow a broader search: ((bernhard OR erhard) OR ((gerhardt OR gerhardtt) OR ggerhard)) ((finckh OR finck ) OR fink )~.
• Adding a wildcard symbol may retrieve word variants: "((bernhard OR erhard) OR ((gerhardt OR gerhardtt) OR ggerhard)) ((finckh" OR finck") OR fink")*.
