Dear all,  
I am running the following query:

curl -XPOST  
"[http://localhost:9200/logstash-2014.11.04/logs/\_search?search\_type=count](http://localhost:9200/logstash-2014.11.04/logs/_search?search_type=count)"  
-d '{  
"aggs": {  
"sessions": {  
"terms": {  
"field": "sessionId",  
"size": 0

```
  },
  "aggs": {
    "sessions_hits": {
      "top_hits": {
        "sort": [
          {
            "@timestamp": {
              "order": "desc"
            }
          }
        ]
      }
    }
  }
}

```

}  
}'

As I read on multiple resources, setting size to 0 should return all  
buckets, however I am still getting 3 buckets per aggregation.

What am I doing wrong here?

Thank you!

Eylül
