Add additional attributes to an existing document elasticsearch

Question

How do I add additional attributes to an existing document in Elasticsearch index.

$ curl -XPUT 'http://localhost:9200/twitter/tweet/1' -d '{
"user" : "kimchy",
"post_date" : "2009-11-15T14:12:12",
"message" : "trying out Elastic Search"
}'

This would create a document in the index. How do I add an attribute to the document? Suppose

"new_attribute":"new_value"

which would modify the document as

"user" : "kimchy",
"post_date" : "2009-11-15T14:12:12",
"message" : "trying out Elastic Search"
"new_attribute" :"new_value"

Answer 1

I think it is possible with the update api. Check this :

https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update.html#_update_part_of_a_document

and scroll down to "add a new field to the document".

I know this is an old post but i think it can be handy

POST /twitter/tweet/1/_update
{
  "doc": {
    "new_attribute":""
  }
}
