Examples of org.apache.lucene.analysis.de.GermanNormalizationFilter

org.apache.lucene.analysis.de.GermanNormalizationFilter
all.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.
- 'ß' is replaced by 'ss'
- 'ä', 'ö', 'ü' are replaced by 'a', 'o', 'u', respectively.
- 'ae' and 'oe' are replaced by 'a', and 'o', respectively.
- 'ue' is replaced by 'u', when not following a vowel or q.
This is useful if you want this normalization without using the German2 stemmer, or perhaps no stemming at all.
