    public final class BrazilianAnalyzer

extends org.apache.lucene.analysis.StopwordAnalyzerBase

`Analyzer` for Brazilian Portuguese language.

Supports an external list of stopwords (words that will not be indexed at all) and an external list of exclusions (words that will not be stemmed, but indexed).

NOTE: This class uses the same `Version` dependent settings as `StandardAnalyzer`.
