How to update a document using elasticsearch-py?

Question

Does anyone have an example for how to use update? It's documented here, but the documentation is unclear and doesn't include a working example. I've tried the following:

coll = Elasticsearch()
coll.update(index='stories-test',doc_type='news',id=hit.meta.id,
                body={"stanford": 1, "parsed_sents": parsed })

and I get

elasticsearch.exceptions.RequestError: 
TransportError(400, u'ActionRequestValidationException[Validation Failed: 1: script or doc is missing;]')

I would like to update using a partial doc, but the update method doesn't take any argument named 'doc' or 'document'.

Solution

You're almost there, you just need to enclose your body inside a "doc" field. The correct way of doing a partial update with elasticsearch-py goes like this:

coll = Elasticsearch()
coll.update(index='stories-test',doc_type='news',id=hit.meta.id,
                body={"doc": {"stanford": 1, "parsed_sents": parsed }})

and what if use this with update_by_query api :) There should be no id parameter I guess.. Or ?

No that's different. update-by-query is an external plugin, not something that is supported by the elasticsearch-py library.

Is it possible use update_by_query in python with http request?

update by query for elasticsearch-py documentation is here elasticsearch-py.readthedocs.io/en/master/…

If you are using elasticsearch 7x - remember to remove doc_type
