How to bulk update a single field in elasticsearch using python

How to perform a single field bulk update in elastic search. Currently, I am trying with helper function as follows,

from elasticsearch import Elasticsearch, helpers
for doc in collection_1:

   try:
       uid = int(doc["uid"])
       k.append({
                "_index": "col1",
                "_type" : "col1",
                "_id"   : uid,
                "_source": doc
            })
    except Exception as err:
       print(err)

helpers.bulk(es, k)

E.S version: 2.4

You could use script for updating just required fields not all _source document

"script": {
    "source": "ctx._source.datetime2=new Date((long)(ctx._source.creationDate+12600000));"
    ,"lang": "painless"
}

Please show your import and and your Elasticsearch version. Also your code is missing a reference to collection1 variable. If you want to use the bulk helpers, you shall follow the syntax described in the python bulk helpers documentation.

You shall specify a field _op_type in your body and set it to update and then pass your partial document.
