Hi,
I'm upgrading our elastic search code to 6.2 and on the python client we use the following API: http://elasticsearch-py.readthedocs.io/en/master/api.html, particularly "put_script". Whereas before we would be able to pass the language in which the script is written as a parameter now I don't find any way of setting that property. I was expecting that if not specified "painless" would be the default value but when posting the script via the python client "mustache" it's actually what seems to be set/defaulted as that's what it's returned on a query to that newly created script from the command line.
e.g.:
curl http://deves.test.aistemos.com:9200/_scripts/size_active_score
{"_id":"size_active_score","found":true,"script":{"lang":"mustache","source":"{"source":"1 + 5 * 1 + doc['size_active'].value\n"}"}}
I wonder if someone knows how is possible to specify the language of the script using the python java client (conn.put_script(...) )? or I would need to change the script to be written in mustache?
Many thanks,
Gemma
