Class KStemFilter

A high-performance kstem filter for english.

See "Viewing Morphology as an Inference Process" (Krovetz, R., Proceedings of the Sixteenth Annual International ACM SIGIR Conference on Research and Development in Information Retrieval, 191-203, 1993).

All terms must already be lowercased for this filter to work correctly.

Note: This filter is aware of the Lucene.Net.Analysis.TokenAttributes.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
