Class GermanStemFilter

A Lucene.Net.Analysis.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 SetKeywordMarkerFilter or a custom Lucene.Net.Analysis.TokenFilter that sets the KeywordAttribute before this Lucene.Net.Analysis.TokenStream.
