Hello.  
I am querying my ES using Logstash.  
I want to output the id of the record from ES into my csv file.

> "\_index": "data",  
> "\_type": "default",  
> **"\_id": "vANfNGYB9XD0VZRJUFfy",**  
> "\_version": 1,  
> "\_score": null,  
> "\_source": {  
> ....

> output { csv {  
> fields =\> ["field1", "field2", "field3", "\_id"]  
> path =\> "/tmp/export.%{+YYYY-MM-dd-hh}.csv"  
> }  
> }

but the \_id is never logged to my csv. All other fields are there as expected, but the special metadata \_id field is not there.  
How can I get it there? I do not want to edit 60+ pipelines I have just to clone one field into another.

Found solution:

When we query ES we have to enable docinfo =\> true. By default it is false.

```auto
input {
 elasticsearch {
  hosts => [your hosts]
  index => "ti"
  query => '{your query}'
  size => 1000
  scroll => "1s"
  docinfo => true
  schedule => "14 * * * *"
 }
}

```

We can than access the metadata with syntax:  
"[@metadata][\_id]",
