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