• If you are trying to use Boolean operators, they must be ALL CAPS: ((bernhard OR erhard) OR (ggerhardt OR ((gerhardt OR eberhardt) OR gebhard))) (finckh OR fink )*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bernhard OR erhard) OR (ggerhardt OR ((gerhardt OR eberhardt) OR gebhard))) (finckh OR fink )*".
