• Performing a fuzzy search may retrieve terms with similar spellings: "((karl ernst) OR (keil ernst)) (bohn" OR sohn")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((karl ernst) OR (keil ernst)) (bohn\" OR sohn\")*".
• Removing quotes may allow a broader search: ((karl ernst) OR (keil ernst)) (bohn OR sohn )*.
