Class MorfologikFilter

Lucene.Net.Analysis.TokenFilter using Morfologik library to transform input tokens into lemma and morphosyntactic (POS) tokens. Applies to Polish only.

MorfologikFilter contains a MorphosyntacticTagsAttribute, which provides morphosyntactic annotations for produced lemmas. See the Morfologik documentation for details.
