    // 其他字段和对应的getter/setter方法
}

import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;

public interface YourEntityRepository extends ElasticsearchRepository<YourEntity, Long> {
    // 可以自定义查询方法
}

@Service

    @Autowired
    private YourEntityRepository repository;

    public List<YourEntity> search(String keyword) {
        // 使用YourEntityRepository提供的搜索方法进行全文搜索
        return repository.findByField1OrField2(keyword, keyword);
    }
