Class HunspellStemFilter

Lucene.Net.Analysis.TokenFilter that uses hunspell affix rules and words to stem tokens.
Since hunspell supports a word having multiple stems, this filter can emit multiple tokens for each consumed token

Note: This filter is aware of the KeywordAttribute. To prevent certain terms from being passed to the stemmer IsKeyword should be set to true in a previous Lucene.Net.Analysis.TokenStream. Note: For including the original term as well as the stemmed version, see KeywordRepeatFilterFactory

This is a Lucene.NET EXPERIMENTAL API, use at your own risk
