Hi,

I want to map mappings for documents in index. For that, I have created mappings with properties as of now.  
But I also want to get the size of documents, for that, I found out that I need to enable "\_size" field as shown here :  
[https://www.elastic.co/guide/en/elasticsearch/plugins/current/mapper-size-usage.html](https://www.elastic.co/guide/en/elasticsearch/plugins/current/mapper-size-usage.html)

My mappings object look like this as of now:

```auto
{
	"mappings": {
		"doc": {
			"properties": {
				...
			}
		}
	}
}

```

where should I add "\_size" tag?  
If I do something like this :-

```auto
{
	"mappings": {
		"doc": {
			"properties": {
				...
			},
            "_size": {
	           	"enabled": true
            }
		}
	}
}

```

I get parsing exception.

If I place it inside properties, I cant get desired results.

Please Help.

Thanks

It looks good.  
You need to share the full error.

Make sure you installed the plugin and restarted your nodes.
