what if for long type filed, i found can set a long filed as follow, i set index to false, and then i put a recored to the index, and then i can agg on this long filed. so, i guess if es build doc values fo this field?

PUT my_index_xxx
{
  "mappings": {
    "my_type": {
      "properties": {
        "customer_token": {
          "type":       "long",
          "index": "false" 
        }
      }
    }
  }
}

POST my_index_xxx/my_type
{
  "customer_token":"10"
}


GET my_index_xxx/my_type/_search
{
  "aggs": {
    "NAME": {
      "terms": {
        "field": "customer_token",
        "size": 10
      }
    }
  }
}

and the search result is:
{
  "took" : 1,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : 1,
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "my_index_xxx",
        "_type" : "my_type",
        "_id" : "st4YTWkBHyBYKlyphyhi",
        "_score" : 1.0,
        "_source" : {
          "customer_token" : "10"
        }
      }
    ]
  },
  "aggregations" : {
    "NAME" : {
      "doc_count_error_upper_bound" : 0,
      "sum_other_doc_count" : 0,
      "buckets" : [
        {
          "key" : 10,
          "doc_count" : 1
        }
      ]
    }
  }
}

Yes. Doc values are activated by default on numbers. See https://www.elastic.co/guide/en/elasticsearch/reference/6.6/number.html#number-params

Doc values don't exist on text type. See https://www.elastic.co/guide/en/elasticsearch/reference/6.6/text.html
