Hi All,

I want to aggregate an index in elasticsearch using logstash and store that aggregate result in another index.

```auto
input {
  elasticsearch {
    hosts => "http://50.254.92.204:9200" 
    user => "elastic"
    password => "changeme"	
    index => "students"
    query => '{"query" : {"constant_score" : {"filter" : {"match" : { "name" : "Vinoth" }}}},"size": 0,"aggs": {"Vinoth_avg_marks": {"avg" : { "field" : "mark" } }}}'
	size => 500 
    scroll => "5m" 
    docinfo => true
  }
}

filter {

}
output {

  stdout { codec => rubydebug } 

  elasticsearch {
    hosts => "50.254.92.204:9200" 
    user => "elastic"
    password => "changeme"	  
    index => "test" 
    document_type => "test"
    #document_id => "%{[@metadata][_id]}"
  }
}

```

But aggregate result is not being pushed into the test index.

Thanks in advance
