如何在ElasticSearch中将价格范围与嵌套查询一起使用？

Question

如何在弹性搜索查询中使用价格范围

这是我的查询：

{
  "query": {
    "nested": {
      "path": "prices",
      "query": {
        "bool": {
          "must": {
            "range": {
              "prices.price": {
                "gte": 1000,
                "lte": 4000
              }
            }
          }
        }
      }
    }
  }
}

这里是索引

  "took": 8,
  "timed_out": false,
  "_shards": {
    "total": 1,
    "successful": 1,
    "skipped": 0,

  },

    "total": 4,

不是基于范围来计算结果数据。如果我{'gte'：0，'lte'：4000}，那么它可以正常工作。如果我使用的是{'gte'：1000，'lte'：4000 }，然后它还会返回数据。某些网站要求使用“ to”和“ from”，但是使用相同的结果会得到相同的结果。
