Delete Document on Elasticsearch

Sometimes we made a mistake on document that we uploaded to Elasticsearch. It is probably possible to update the document with a new one. However, deleting the documents are probably a better and cleaner option.

To do that on Elasticsearch, we can execute the query below,

curl -X POST "localhost:9200/twitter/_delete_by_query?scroll_size=5000" -H 'Content-Type: application/json' -d'

{

  "query": {

    "term": {

      "user": "kimchy"

    }

  }

}

'

Scross_size may be required because otherwise It would only delete 1000 documents.
