Class GreekStemFilter

  extended by org.apache.lucene.util.AttributeSource
      extended by org.apache.lucene.analysis.TokenStream
          extended by org.apache.lucene.analysis.TokenFilter
              extended by org.apache.lucene.analysis.el.GreekStemFilter
All Implemented Interfaces:

public final class GreekStemFilter
extends TokenFilter

A TokenFilter that applies GreekStemmer to stem Greek words.

To prevent terms from being stemmed use an instance of KeywordMarkerFilter 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.

WARNING: This API is experimental and might change in incompatible ways in the next release.
