public final class GermanStemFilter
extends org.apache.lucene.analysis.TokenFilter
TokenFilter that stems German words.
It supports a table of words that should
not be stemmed at all. The stemmer used can be changed at runtime after the
filter object is created (as long as it is a GermanStemmer).
To prevent terms from being stemmed use an instance of
KeywordMarkerFilter or a custom TokenFilter that sets
the KeywordAttribute before this TokenStream.
