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