    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.
