Hello!  
I need to get id in previous document.

My query:  
query.json

> {  
> "size" : 1,  
> "sort" : [{"timestamp": "desc"}],  
> "query": {  
> "query\_string": {  
> "query": "AS:%{[name]}"  
> }  
> },  
> "\_id": "%{[@metadata][\_id]}"  
> }

But i can't get **id**. What wrong?

Maybe there is another way get \_id in previous doc in logstash?

If you are using an elasticsearch input you can use the docinfo option to have the input add the document id to each event.
