Class GreekAnalyzer

      org.apache.lucene.analysis.Analyzer

    public final class GreekAnalyzer

extends StopwordAnalyzerBase

`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 `Version` 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 `Version` dependent settings as `StandardAnalyzer`.
