elasticsearch 带过滤和聚合的Elasricsearch查询

我有一个包含简单汽车广告数据的Elasticsearch索引。我制作了一张地图：

"mappings": {
"properties": {
  "brand": {"type": "keyword"},
  "model": {"type": "keyword"},
  "year of production": {"type": "integer"},
  "mileage": {"type": "integer"},
  "color": {"type": "keyword"},
  "engine capacity": {"type": "double"},
  "horse power": {"type": "integer"}, 
  "type of fuel": {"type": "keyword"},
  "condition": {"type": "keyword"},
  "accident history": {"type": "boolean"},
  "price": {"type": "integer"}
  }
}

我想创建两个查询：

显示2010年至2012年制造的二手车的平均里程

展示2005年至2007年间最受欢迎的车型，里程数超过200000

我尝试创建这两个查询，下面是我尝试第一个查询的结果：

GET /gielda/_search?pretty
{ 
  "query": {
    "match": {
      "stan": "Used"
  }
}, 
"aggs": {
  "production_ranges": {
    "range": {
      "field": "year of production",
      "ranges": [
        {
          "from": 2010,
          "to": 2012
        }
      ]
    },
    "aggs": {
      "avg_mileage": {
        "avg": {
          "field": "mileage"
        }
      }
    }
  }
 }
}

---

我发现这个查询无法正常工作。我在弹性文档和堆栈中寻找答案，但我仍然不知道如何将聚合与筛选器或范围混合使用。

您需要使用、、和聚合的组合
