如何在弹性搜索中使用查询构建器仅从嵌套类中获取匹配的数据? [英] How to get only matched data from nested class using query builder in elastic search?

问题描述

我试图仅从弹性搜索类的嵌套数组中获取匹配的数据.但我无法得到它......整个嵌套数组数据正在作为输出返回.

I am trying to get only the matched data from nested array of elastic search class. but I am not able to get it..the whole nested array data is being returned as output.

这是我的查询:-

QueryBuilders.nestedQuery(问题",QueryBuilders.boolQuery().must(QueryBuilders.matchQuery(questions.questionTypeId", quesTypeId)), ScoreMode.None).innerHit(new InnerHitBuilder());

QueryBuilders.nestedQuery("questions", QueryBuilders.boolQuery() .must(QueryBuilders.matchQuery("questions.questionTypeId", quesTypeId)), ScoreMode.None) .innerHit(new InnerHitBuilder());

我正在使用查询构建器从嵌套类中获取数据.它工作正常，但无法仅获取匹配的数据.

I am using querybuilders to get data from nested class.Its working fine but not able to get only the matched data.

请求正文:{问题类型 ID":MCMC"}

Request Body : { "questionTypeId" : "MCMC" }

当 questionTypeId = MCMC"时；这是我得到的输出..在这里我想排除 questionTypeId = "SCMC" 的输出.

when questionTypeId = "MCMC" this is the output i am getting..Here I want to exclude the output for which the questionTypeId = "SCMC".

输出:

   {
    "id": "46",
    "subjectId": 1,
    "topicId": 1,
    "subtopicId": 1,

        }
    ]
}

推荐答案

因为你已经用 spring-data-elasticsearch:

最近在 4.1.M1 版本中添加了对返回内部命中的支持，因此将包含在下一个发布版本中.然后在 SearchHit 中，您将获得完整的顶级文档，但在 innerHits 属性中，只会返回匹配的内部命中.

Support to return inner hits was recently added to version 4.1.M1 and so will be included in the next released version. Then in a SearchHit you will get the complete top level document, but in the innerHits property only the matching inner hits will be returned.
