How to include _version in scroll / scan results?

Elastic Stack Elasticsearch
1

Hello ES folks!

I'd like to see _version included in the results for my scan / scroll search query. I don't see it included in the default results when I query for full records, nor if I request it in the _source array. I do see the _version when I retrieve an individual row.

Is _version available via the sroll interface? Am I doing something wrong in this query?

I originally wrote my code against a 1.x version of ES. I am using elasticsearch 2.1 in production.

Here are direct curl versions similar to our requests.

query versions

  1. search_type=scan

     #!/bin/sh
 ES_HOST=localhost
 SCROLL_ID=$(curl http://$ES_HOST:9200/resumes-test/resume/_search'?search_type=scan&scroll=10m' -d'{ "query":{ "match_all": {} }}' | jq -r '.["_scroll_id"]')
 curl http://$ES_HOST:9200/_search/scroll\?scroll\=1m -d $SCROLL_ID > scan_scroll_test.json

  2. scroll

     #!/bin/sh
 ES_HOST=localhost
 curl http://$ES_HOST:9200/resumes-test/resume/_search'?scroll=1m' -d '{"query":{"match_all": {}}}' > scroll_test.json

Wow, is it really just that I was missing "version": true in my request?
