ElasticSearch aggregation counting query

Question

I have got the following document:

"_index": String,
"_type": String,
"_id": String,
"_source": {
    "id": String
    "sendDate": Date
    "title": String
    "author": String
    "language": String
    "keywords": Array<String>
}

I would like list and count every single keyword from whole type from database. Have you maybe any tips for me?

I created sth like below { "size": 0, "aggs": { "item": { "terms": { "field": "keyWords","size": 1000000 } }, "total_terms": { "cardinality": { "field": "keyWords" } } } } but it shows only single words, sometimes keyword is built from a few words — Jo Dung

it would be great if you edit your question and add the result you get and the result you expect. — Taras Kohut

So here is the answer

{
      "size": 0,
      "aggs": {
        "item": {
          "terms": {
            "field": "keyWords.raw",
            "size": 1000000
          }
        },
        "total_terms": {
          "cardinality": {
                "field": "keyWords.raw"
          }
        }
      }
}
