How can I write these following query in kibana?

SELECT distinct description FROM customers;
select description,count(*) from customers;

I am trying with following but not getting expected result.

1st Query

GET customers/_search
{
  "aggs": {
    "distinct_terminals": {
      "cardinality": {
        "field":"description" // and tried with "description.keyword"
      }
    }
  }
}

2nd Query

GET customers/_search{
"size": 0,
  "aggs": {
    "country_detail": {
      "terms": {
        "field": "Country.keyword"
      }
    }
  }
}

2nd query return result as expected but when I was trying to perform this query on a field like a description. it stops working. i.e.

GET customers/_search{
"size": 0,
  "aggs": {
    "description_detail": {
      "terms": {
        "field": "Description.keyword"
      }
    }
  }
}

Description cannot be 2 3 words. it should be more than that, maybe in a paragraph.

It sounds like your "Description" field is mapped as { "type": "text" } in Elasticsearch. text fields can not be used with Terms aggregations. You might consider re-mapping your Description field in one of two ways:

  1. Enable fielddata on the "Description" field; or
  2. Re-map the "Description" field as both a text field and keyword field using the fields parameter.

Note, this may dramatically increase your index size.
