Elasticsearch 按 ID 数组查询返回的结果不是按传入的 id 数组排序的 - elasticsearch query by array of id result returned is not sorted by the array of id pass in

elasticsearch query by array of id result returned is not sorted by the array of id pass in

我正在使用弹性体，下面是我的查询：

    $query = new Query();
    $query->setSize(5);
    $qb = new 'Elastica'Query'Ids();
    $qb->addId("id_5");
    $qb->addId("id_3");
    $qb->addId("id_4");
    $qb->addId("id_1");
    $qb->addId("id_2");
    return $query->setQuery($qb)

我希望结果返回的顺序与我传入的顺序相同，例如在这种情况下，它将是"id_5、id_3、id_4、id_1、id_2"

但是我得到的是排序与我想要的不一样

我认为这是两个解决方案1.如果您有ID作为文件的一部分，那么您可以做

POST indexName/_search
{
  "sort": [
    {
      "_script": {
        "type": "number",
        "script": "sortOrder.indexOf(doc['Id'].value)",
        "params": {
          "sortOrder": [
            "AVMX9sHTyNVr4SjF3oRt",
            "AVMTc1fSyNVr4SjF3WpF",
            "AVMYuGLOyNVr4SjF3rKm"
          ]
        },
        "order": "asc"
      }
    }
  ],
  "query": {
    "ids": {
      "values": [
        "AVMX9sHTyNVr4SjF3oRt",
            "AVMTc1fSyNVr4SjF3WpF",
            "AVMYuGLOyNVr4SjF3rKm"
      ]
    }
  }
}

如果没有，则需要将类型的映射更新为

{
  "mappings": {
    "YOUR_TYPE": {
      "_id": {
        "index": "not_analyzed"
      }
    }
  }
}

然后你可以使用"script"："sortOrder.indexOf（doc['_id'].value）"
