Need to return source fields only, without any metadata - how to use plugin?

We have a requirement that we return just the source fields in search results, without any of the metadata. From searching, I gather that this is not possible with elasticsearch, but I did find a reference to maybe using a plugin in this thread:

Filter out metadata fields and only return source fields in elasticsearch

The plugin that was linked was this one:

https://github.com/imotov/elasticsearch-just-source/blob/master/src/main/java/org/elasticsearch/examples/justsource/rest/action/RestJustSourceAction.java

I'm still learning about elasticsearch, but can someone explain how I would implement and deploy that plugin in our elasticsearch configuration?

Thanks, Jim

As stated in the first link you referenced, it is possible to do it with response filtering which is not a plugin but a standard feature of ES:

GET /index/type/_search?filter_path=hits.hits._source

If you want to get rid of hits.hits._source you can use jq

curl -XGET localhost:9200/index/type/_search?filter_path=hits.hits._source | jq '.hits.hits[]._source'
