• Performing a fuzzy search may retrieve terms with similar spellings: (((((("kranich <zahl>") OR ("kranich <wahlt>"))) OR ("kranich <nahm>"))) OR ("kranich <wahl>"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"kranich <zahl>\") OR (\"kranich <wahlt>\"))) OR (\"kranich <nahm>\"))) OR (\"kranich <wahl>\"))*".
• Removing quotes may allow a broader search: (((((( kranich <zahl> ) OR ( kranich <wahlt> ))) OR ( kranich <nahm> ))) OR ( kranich <wahl> ))*.
