SnowballFilter
with
RussianStemmer
instead, which has the
same functionality. This filter will be removed in Lucene 4.0@Deprecated public final class RussianStemFilter extends org.apache.lucene.analysis.TokenFilter
TokenFilter
that stems Russian words.
The implementation was inspired by GermanStemFilter.
The input should be filtered by LowerCaseFilter
before passing it to RussianStemFilter ,
because RussianStemFilter only works with lowercase characters.
To prevent terms from being stemmed use an instance of
KeywordMarkerFilter
or a custom TokenFilter
that sets
the KeywordAttribute
before this TokenStream
.
