• Performing a fuzzy search may retrieve terms with similar spellings: ((rolf OR roll) OR (proof OR root)) ((henne OR henner ) OR hennes )~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((rolf OR roll) OR (proof OR root)) ((henne OR henner ) OR hennes ).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((rolf OR roll) OR (proof OR root)) ((henne OR henner ) OR hennes )".
• Adding a wildcard symbol may retrieve word variants: ((rolf OR roll) OR (proof OR root)) ((henne OR henner ) OR hennes )*.
