I'm using ES 6.3, I want to find size of a document using script.  
I've tried:  
`"script": "doc.toString().length()"`  
But doc.toString() is classname `org.elasticsearch.search.lookup.LeafDocLookup@57b1c349`.

I know I can enable \_size by using size-mapper plugin, but don't have access to that, but scripting is enabled, so how can I do this?

Can you explain, what you are trying to achieve? You could try using a script ingest processor and just take the length of the `toString()` representation of the ctx map, however this would not be accurate, as it is not the original JSON.

Interested in the use-case here.

@spinscale, I want to know total size of raw documents per day in the index. If I had the \_size enabled I would do search query like:

```
{
  "size": 0,
  "aggs" : {
    "size_per_day" : {
        "date_histogram" : {
            "field" : "@timestamp",
            "interval" : "day"
        },
        "aggs": {
            "size": {
                "sum": {
                    "field": "_size" # Want to use script to find size
                }
            }
        }
    }
  }
}

```

Also I can't use index stats as it will have the compressed size. Please let me know If there is any other way.

Thanks,
