Answer 1

To update the excellent answer from Andrei Stefan, we need to say that the query parameter search_type=count is no more supported in Elasticsearch 5. The new way of doing this is to add "size" : 0 in the body such as :

GET /cars/transactions/_search
{
  "size": 0,
  "aggs": {
    "distinct_colors": {
      "terms": {
        "field": "color",
        "size": 1000
      }
    }
  }
}
