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