Deprecated.
(3.1) Use SnowballFilter with DutchStemmer instead, which has the same functionality. This filter will be removed in Lucene 5.0

A TokenFilter that stems Dutch 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 DutchStemmer).

To prevent terms from being stemmed use an instance of KeywordMarkerFilter or a custom TokenFilter that sets the KeywordAttribute before this TokenStream.
