• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((carl OR call) OR carlo) (hermann OR herman) (ethe\" OR (pethe\" OR pether\"))~".
• Removing quotes may allow a broader search: ((carl OR call) OR carlo) (hermann OR herman) (ethe OR (pethe OR pether ))~.
• Adding a wildcard symbol may retrieve word variants: "((carl OR call) OR carlo) (hermann OR herman) (ethe" OR (pethe" OR pether"))*.
