Can I use MongoRepository to sort in the order of the score?

问题

I'm going to sort the search results in the database in the order of the score.

However, I could not find a way to sort using mongoRepository, so I asked a question.

Is there a way to sort by score using MongoRepository?

This is my Entity:

@Data
@Document(collection = "cad")
public class Cad {
    @Id
    private String id;
    private String author;
    private String mainCategory;
    private String subCategory;
    private String title;
    private String index;
    private String s3Url;
    private String createdAt;

    public Cad(String author, String mainCategory, String subCategory, String title, String index, String s3Url, String createdAt) {
        this.author = author;
        this.mainCategory = mainCategory;
        this.subCategory = subCategory;
        this title = title;
        this.index = index;
        this.s3Url = s3Url;
        this.createdAt = createdAt;
    }
}

And This is my Repository:

public interface CadRepository extends MongoRepository<Cad, String> {
    List<Cad> findAllByTitleOrIndexOrMainCategoryOrSubCategoryContains(String text1, String text2, String text3, String text4);
}

And This is my Service:

@RequiredArgsConstructor
@Service
@Component
public class CadService {
    private final CadRepository cadRepository;

    public List<Cad> searchCadFile(String searchText) {
        try {
            List<Cad> list = cadRepository.findAllByTitleOrIndexOrMainCategoryOrSubCategoryContains(searchText, searchText, searchText, searchText);
            return list;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
}

I tried @Aggregate Annotation, but I didn't get the result I wanted.

Any hint would be appreciated. Thank you 你可以使用 MongoRepository 来按分数的顺序排序吗?

得分: 1

你可以在你的存储库方法中添加一个 org.springframework.data.domain.Sort 参数:

List<Cad> findAllByTitleOrIndexOrMainCategoryOrSubCategoryContains(String text1, String text2, String text3, String text4, Sort sort);

当调用你的存储库方法时,你可以添加要排序的属性:

List<Cad> list = cadRepository.findAllByTitleOrIndexOrMainCategoryOrSubCategoryContains(searchText, searchText, searchText, searchText, Sort.by("index"));

或者,你可以将属性添加到方法名称中:

List<Cad> findAllByTitleOrIndexOrMainCategoryOrSubCategoryContainsOrderByIndexAsc(String text1, String text2, String text3, String text4);

更详细的解释可以在这里找到:https://www.baeldung.com/spring-data-sorting

英文:

You can add a org.springframework.data.domain.Sort parameter to your repository method:

List&lt;Cad&gt; findAllByTitleOrIndexOrMainCategoryOrSubCategoryContains(String text1, String text2, String text3, String text4, Sort sort);

And when calling your repository method you can add the property / properties you want to sort on:

List&lt;Cad&gt; list = cadRepository.findAllByTitleOrIndexOrMainCategoryOrSubCategoryContains(searchText, searchText, searchText, searchText, Sort.by(&quot;index&quot;));

Or you can add the property to the method name:

List&lt;Cad&gt; findAllByTitleOrIndexOrMainCategoryOrSubCategoryContainsOrderByIndexAsc(String text1, String text2, String text3, String text4);
