• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((eberhard OR erhard) OR (eberhardt OR (geberhardt OR geberhardtt))) (finckh\" OR fink\")*".
• Removing quotes may allow a broader search: ((eberhard OR erhard) OR (eberhardt OR (geberhardt OR geberhardtt))) (finckh OR fink )*.
