Return _version with query hits

Elastic Stack Elasticsearch
1

I'm using the _version attribute to ensure a put to particular document id
only succeeds if the correct version is specified This works great except I
don't seem to be able to get elasticsearch to return the correct version
with query results.

I'm sending this query:

{"query":{"term":{"accounts.provider_uid":"xxxx","accounts.provider":"xxxx"}},"from":0,"size":1,"fields":["_source","_id","_version","_score"]}

I get one result for the query and the _id, _score, and _source field are
there as expected but the _version field that I would need to update with
the version check enabled is missing.

Am I doing something wrong or is this simply not supported?

Thanks!

That worked. Sort of. I actually found what looks like a bug.

This returns a _version:

{"from":0,"size":1,"version":true,"query":{"term":{"accounts.provider_uid":"xxxx","accounts.provider":"xxxx"}}}

This doesn't:

{"query":{"term":{"accounts.provider_uid":"xxxxxx","accounts.provider":"xxxxx"}},"from":0,"size":1,"version":true}
The queries are identical except for the position of the parameters.

I filed an issue for
this: "version":true only works if it appears before query · Issue #2545 · elastic/elasticsearch · GitHub

This turned out to not be a bug in ES, but the github issue did prompt me
to update my Java client to call SearchRequestBuilder.setVersion(true), and
now my SearchHit objects contain the version number! Thanks, Shay!
