• Performing a fuzzy search may retrieve terms with similar spellings: (((( kranich (<walter> OR <maier> )) OR ( kranich <falter> ))) OR ( kranich <nahm> ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((( kranich (<walter> OR <maier> )) OR ( kranich <falter> ))) OR ( kranich <nahm> ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( kranich (<walter> OR <maier> )) OR ( kranich <falter> ))) OR ( kranich <nahm> ))*".
