public final class RussianStemFilter
- extends org.apache.lucene.analysis.TokenFilter
A TokenFilter
that stems Russian words.
The implementation was inspired by GermanStemFilter.
The input should be filtered by RussianLowerCaseFilter
before passing it to RussianStemFilter ,
because RussianStemFilter only works with lowercase part of any "russian" charset.
