• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((johan fischer) OR (johann fischart))) or (johannes picht))) or (johanna fischer))) or (johannes basch))".
• Adding a wildcard symbol may retrieve word variants: ((((((((johan fischer) OR (johann fischart))) or (johannes picht))) or (johanna fischer))) or (johannes basch))*.
