You may be able to get more results by adjusting your search query.

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