public final class RussianStemFilter
- extends TokenFilter
A filter 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.
