• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((johannes fischer) OR (((johannes picht) OR (johannes wicht))))) OR (johanna fischer))) OR (johannes berchem))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((johannes fischer) or (((johannes picht) OR (johannes wicht))))) or (johanna fischer))) or (johannes berchem))*".
