elasticsearch - Elasticsearch，将嵌套过滤器与普通过滤器结合

Question

我想出了如何在Elasticsearch中映射和过滤嵌套查询。好极了!但是，尚无法解决的是同时过滤“普通”过滤器和嵌套过滤器。您在此处看到的示例没有给出错误，并且第二个(嵌套的)过滤器似乎正在运行，但第一个过滤器却没有。在此示例中，我希望包括两个过滤器，而不仅仅是一个。我究竟做错了什么？

{
  "size": 100,
  "sort": [],
  "query": {
    "filtered": {
      "query": {
        "match_all": []
      },
      "filter": {
        "bool": {
          "must": [
            {
              "terms": {
                "category.untouched": [
                  "Chargers"
                ]
              }
            }
          ],
          "should": [],
          "must_not": {
            "missing": {
              "field": "model"

          }
        }
      },

                        {
                            "term": {
                                "phones.name.untouched":"Galaxy S3 Neo I9301"
                            }
                        }
                    ]
                }
            }

      "terms": {
        "field": "brand.untouched"

Answer 1

您有两个名为"filter"的键(在"filtered"中)，因此其中之一将被忽略。您可能只需要将两个过滤器包装在"bool"中即可( bool(boolean) 值可以根据需要嵌套)。

我无法在不设置一些测试数据的情况下对其进行测试，但是请尝试一下，看看是否能使您更接近:

   "size": 100,
   "sort": [],
   "query": {
      "filtered": {
         "query": {
            "match_all": []
         },
         "filter": {
            "bool": {
               "must": [
                  {
                     "terms": {
                        "category.untouched": [
                           "Chargers"
                        ]
                     }
                  },
                  {
