public final class GreekAnalyzer
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:
NOTE: This class uses the same Version
dependent settings as StandardAnalyzer
.
