• The words AND, OR and NOT may confuse the search; try adding quotes: "(ebgerhard OR ((eberhardt OR ehrhardt) OR ((erhardt OR ggerhardt) OR gerhard))) (finckh OR finck)~".
• Adding a wildcard symbol may retrieve word variants: (ebgerhard OR ((eberhardt OR ehrhardt) OR ((erhardt OR ggerhardt) OR gerhard))) (finckh OR finck)*.
