如何在spring boot中编写以下弹性搜索通配符查询？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

@Document(indexName = "articles", type = "_doc")
public class Article {

    @Id
    private String id;

    @Field(type = FieldType.Text)
    private String title;

    // 其他字段...

    // getter和setter方法...
}

@Repository
public interface ArticleRepository extends ElasticsearchRepository<Article, String> {

    List<Article> findByTitleLike(String keyword);
}

@Service
public class ArticleService {

    @Autowired
    private ArticleRepository articleRepository;

    public List<Article> searchByTitle(String keyword) {
        return articleRepository.findByTitleLike("*" + keyword + "*");
    }
}
