如何在我的Lucene应用程序中使用ASCIIFoldingFilter？

   <groupId>org.apache.lucene</groupId>
   <artifactId>lucene-analyzers-common</artifactId>
   <version>8.10.1</version>
</dependency>

@Override
protected TokenStreamComponents createComponents(String fieldName) {
    Tokenizer source = new StandardTokenizer(input);
    TokenStream result = new ASCIIFoldingFilter(source);
    return new TokenStreamComponents(source, result);
}

// 创建索引
IndexWriterConfig indexWriterConfig = new IndexWriterConfig(new MyAnalyzer());
IndexWriter indexWriter = new IndexWriter(directory, indexWriterConfig);

// 执行查询
IndexSearcher indexSearcher = new IndexSearcher(DirectoryReader.open(directory));
QueryParser queryParser = new QueryParser("fieldName", new MyAnalyzer());
Query query = queryParser.parse("查询内容");
TopDocs topDocs = indexSearcher.search(query, 10);
