public final class GreekStemFilter extends TokenFilter
TokenFilter
that applies GreekStemmer
to stem Greek
words.
To prevent terms from being stemmed use an instance of
SetKeywordMarkerFilter
or a custom TokenFilter
that sets
the KeywordAttribute
before this TokenStream
.
NOTE: Input is expected to be casefolded for Greek (including folding of final
sigma to sigma), and with diacritics removed. This can be achieved by using
either GreekLowerCaseFilter
or ICUFoldingFilter before GreekStemFilter.
