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 <zahmt>" » "kraniche <zahmt>" (Expand Search), "kranich <zahlt>" (Expand Search), "kranich <zahm>" (Expand Search)
"kranich <kalter>" » "kraniche <kalter>" (Expand Search), "kranich <walter>" (Expand Search), "kranich <alter>" (Expand Search), "kranich <kater>" (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 <zahmt>\") OR (\"kranich <kalter>\"))))) OR (\"kranich <nahm>\"))~".
• Removing quotes may allow a broader search: (((( kranich <zahl> ) OR ((( kranich <zahmt> ) OR ( kranich <kalter> ))))) OR ( kranich <nahm> ))~.
• Adding a wildcard symbol may retrieve word variants: (((("kranich <zahl>") OR ((("kranich <zahmt>") OR ("kranich <kalter>"))))) OR ("kranich <nahm>"))*.
