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