Parameters in inline script

Elastic Stack Elasticsearch
1

Hi, does below query ever work in Elasticsearch 5.x?

"inline": "doc['my_field'] * multiplier",
"params": {
"multiplier": 2
}

Whenever I use parameters in query I always got compile errors. The query is from documentation:
https://www.elastic.co/guide/en/elasticsearch/reference/5.1/modules-scripting-using.html#reload-scripts

It turns out the Elasticsearch documentation is wrong, you should add "params." in front of the variables in order to access its values.
