Spring Boot &弹性搜索 |多索引搜索功能 [英] Spring Boot & Elastic Search | Multi-index search functionality

问题描述

我有一个 spring boot API，它有三个模型(用户、项目、技能)，目前我可以毫无问题地搜索任何索引，如下所示:

I have a spring boot API which has three models (User, Projects, Skills) currently I can search any of the indexes without issue as below:

  log.info("Search with query {}", query);
        Pageable pageable = PageRequest.of(page, size);

        QueryBuilder queryBuilder =
                QueryBuilders
                        .multiMatchQuery(query, "projectDescription", "projectName", "projectTechStack")
                        .fuzziness(Fuzziness.ONE);

        Query searchQuery = new NativeSearchQueryBuilder()
                .withFilter(queryBuilder)
                .withPageable(pageable)
                .build();

        SearchHits<UserProjects> projectHits =
                elasticsearchOperations
                        .search(searchQuery, UserProjects.class,
                                IndexCoordinates.of(elasticProjectsIndex));

但是我想搜索所有三个索引并将它们映射到正确的 POJO.我比较坚持这一点.此外，这就是我非常困惑的地方，我想要一个分页的响应，其中包含以下内容:

However I would like to search all three indices and map them to the correct POJO. I'm rather stuck on this. Furthermore and this is where I get VERY stuck is, I would like to have a response paginated which would contain lets say the following:

User results: 3 of 100 
Project Results 4 of 10
etc etc

基本上，在我的前端，我可以知道是否应该显示单击此处查看更多用户结果"；将仅在用户索引上运行搜索的链接.

Basically so on my front end I can know if I should show a "click here for more User results" link which would run a search just on the user index.

如果有人可以帮助我，那就太棒了.

If anyone can please help me that would be amazing.

谢谢

推荐答案

如果用户想要跨多个维度/索引进行搜索，那么 MultiSearch 将非常有用.

If a user wants to search across multiple dimensions/indexes then MultiSearch will be very useful.

示例用法: 用户可以亲自搜索java"，文章&职位索引(在 LinkedIn 类型的应用程序中)，并且能够根据请求配置分页.

Example Usage: User can search for 'java' in person, article & job indices (in a LinkedIn type application) and would be able to configure pagination per request.
