Perhaps you should try some spelling variations:
"kranich <zahl>" » "kraniche <zahl>" (Expand Search), "kranich <zahlt>" (Expand Search), "kranich <wahl>" (Expand Search), "kranich <kahl>" (Expand Search)
"kranich <kahlt>" » "kraniche <kahlt>" (Expand Search), "kranich <kahl>" (Expand Search), "kranich <zahlt>" (Expand Search), "kranich <kalt>" (Expand Search)
"kranich <kahle>" » "kraniche <kahle>" (Expand Search), "kranich <fahle>" (Expand Search), "kranich <kahl>" (Expand Search)
"kranich <nahm>" » "kraniche <nahm>" (Expand Search)

You may be able to get more results by adjusting your search query.

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