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