GET usernested/_search
{
  "query": {
    "nested": {
      "path": "tags",
      "query": {
        "bool": {
          "must": [
            {
              "term": {
                "tags.brandid": "93a8296c-5b64-49ea-bd92-b19192def2e9"
              }
            },
            {
              "term": {
                "tags.site": "163"
              }
            }
          ]
        }

//按照条件新建一个index 作为测试数据使用
POST _reindex
{
  "source": {
    "index": "usernested",
    "query": {
      "nested": {
        "path": "tags",
        "query": {
          "bool": {
            "must": [

        }
      }
    }
  },
  "dest": {
    "index": "new_usernested"
