> Key: LUCENE-5275
> URL: https://issues.apache.org/jira/browse/LUCENE-5275
> Project: Lucene - Core

> Its currently just Object.toString, e.g.:
> org.apache.lucene.analysis.en.PorterStemFilter@8a32165c
> But I think we should make it more useful, to end users trying to see what
> their chain is doing, and to make SOPs easier when debugging:
> {code}
> EnglishAnalyzer analyzer = new EnglishAnalyzer(TEST_VERSION_CURRENT);
> try (TokenStream ts = analyzer.tokenStream("body", "Its 2013, let's fix this
> already!")) {
> ts.reset();
> while (ts.incrementToken()) {
> System.out.println(ts.toString());
> }
> ts.end();
> }
> {code}
> Proposed output:
> {noformat}
