Spring数据MongoDB（v4.4.1）文本搜索不工作

我正在使用SpringDataMongoDB。我尝试使用

TextCriteria

类进行文本搜索，但没有改进。我有以下文件

@Document(collection="books")
public class Book {

    @Id
    private String id;
    
    @TextIndexed(weight=2)
    private String title;
    
    @TextIndexed
    private String name;
     
    private String bookCode;
    
    @TextScore
    private Float score;
    //getters & setters
}

我的serviceImpl类是

@Autowired MongoTemplate template;

@Override
public List<Book> searchBookDetails(String searchString) {
    TextCriteria criteria = TextCriteria.forDefaultLanguage()
              .matchingAny("Tamil", "English");
    Query query = TextQuery.queryText(criteria)
              .sortByScore();
    List<Book> r = template.find(query, Book.class);
    return r;
}

我不知道如何解决这个问题。我在下面的链接中找到了这部分代码

您是否验证了文本索引是在MongoDB中创建的？如果它没有使用注释创建索引，请使用mongoTemplate上的手动ensureIndex。我也手动创建了索引，但没有使用。我在这里遗漏的任何其他东西它在4.0版本中运行良好，而且我在手动创建索引时也发现了问题

db.books.createIndex（{title:“text”，name:“text”}）
