public final class GreekStemFilter extends TokenFilter
ATokenFilterthat appliesGreekStemmerto stem Greek words.To prevent terms from being stemmed use an instance of
SetKeywordMarkerFilteror a customTokenFilterthat sets theKeywordAttributebefore thisTokenStream.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
GreekLowerCaseFilteror ICUFoldingFilter before GreekStemFilter.- WARNING: This API is experimental and might change in incompatible ways in the next release.
