• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((((\\"kranich (<walt>\\" OR <walther>\\")) OR (\\"kranich <nahm>\\"))) OR (\\"kranich <zahl>\\"))~\"".
• Removing quotes may allow a broader search: (((( kranich (<walt> OR <walther> )) OR ( kranich <nahm> ))) OR ( kranich <zahl> ))~.
