Class GermanNormalizationFilter

Normalizes German characters according to the heuristics of the http://snowball.tartarus.org/algorithms/german2/stemmer.html German2 snowball algorithm. It allows for the fact that ä, ö and ü are sometimes written as ae, oe and ue.

This is useful if you want this normalization without using the German2 stemmer, or perhaps no stemming at all.
