chenhh021 opened a new issue, #780: URL: https://github.com/apache/lucenenet/issues/780
See [Lucene-10008](https://issues.apache.org/jira/browse/LUCENE-10008). It's also valid for lucene. CommonGramsFilterFactory's use of the "words" and "ignoreCase" config options is inconsistent with how StopFilterFactory uses them - leading to "ignoreCase=true" not being respected unless "words" is specified. Reproduce: ``` c# [Test] public void testIgnoreCase() { IResourceLoader loader = new ClasspathResourceLoader(typeof(TestAnalyzers)); CommonGramsFilterFactory factory = (CommonGramsFilterFactory) TokenFilterFactory("CommonGrams", TEST_VERSION_CURRENT, loader, "ignoreCase", "true"); CharArraySet words = factory.CommonWords; assertTrue("words is null and it shouldn't be", words != null); assertTrue(words.contains("the")); //passes assertTrue(words.contains("The")); //fails Tokenizer tokenizer = new MockTokenizer(new StringReader("testing the factory"),MockTokenizer.WHITESPACE, false); TokenStream stream = factory.Create(tokenizer); AssertTokenStreamContents( stream, new String[] {"testing", "testing_The", "The", "The_factory", "factory"}); } ``` Working for a PR now. -- This is an automated message from the Apache Git Service.
