Class GreekAnalyzer

Lucene.Net.Analysis.Analyzer for the Greek language.

Supports an external list of stopwords (words that will not be indexed at all). A default set of stopwords is used unless an alternative list is specified.

You must specify the required Lucene.Net.Util.LuceneVersion compatibility when creating GreekAnalyzer:

  • As of 3.1, StandardFilter and GreekStemmer are used by default.
  • As of 2.9, StopFilter preserves position increments

NOTE: This class uses the same Lucene.Net.Util.LuceneVersion dependent settings as StandardAnalyzer.
