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