public final class FrenchAnalyzer
Analyzer
for French language.
Supports an external list of stopwords (words that will not be indexed at all) and an external list of exclusions (word that will not be stemmed, but indexed). A default set of stopwords is used unless an alternative list is specified, but the exclusion list is empty by default.
You must specify the required Version
compatibility when creating FrenchAnalyzer:
NOTE: This class uses the same Version
dependent settings as StandardAnalyzer
.
