The following aggregation starts returning empty buckets while it returns the actual rows.  
{ "aggs": { "contact\_ids": { "terms": { "field": "contact\_id" } }}}

It starts returning the buckets properly after clearing the cache this way.  
curl -XPOST '[http://cluster.host:9200/\_cache/clear](http://cluster.host:9200/_cache/clear)' -d '{ "fielddata": "true" }'

But all this happens again after a while. Why does it fail silently? How to fix that?  
We have 6 nodes with 32Gb of memory each (16Gb for ES), 6 indexes with 5 shards each  
and around 200 million documents.

Check your logs, you may see something about circuit breaker there.

We don't have any exceptions in our logs.

Could this mapping be an issue?  
One contact\_id has doc\_type: true, the other one does not.  
if contact\_id does have one fielddata fields for both types  
how then elasticsearch will decide if it need to use doc\_values?

```
           contact: {
              properties: {
                contact_id: { type: 'long', index: 'not_analyzed'}
              }
            },
            event: {
              _parent: { type: :contact },
              properties: {
                user_id: { type: 'long', index: 'not_analyzed' },
                contact_id: { type: 'long', index: 'not_analyzed', doc_values: true },
                data: { type: 'object', index: 'not_analyzed' },
              }
            }
```

Could you show us what the response you get looks like?

Query:

```
POST events_production_2015_04/contact/_search
{
    "query": {
        "filtered": {
            "filter": {
                "bool": {
                    "must": []
                }
            }
        }
    },
    "aggs": {
        "contact_ids": {
            "terms": { "field": "contact_id" }
        }
    }
}

```

Response:

```
{
   "took": 240,
   "timed_out": false,
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },
   "hits": {
      "total": 3614637,
      "max_score": 1,
      "hits": [
         {
            "_index": "events_production_2015_04",
            "_type": "contact",
            "_id": "12094631113617",
            "_score": 1,
            "_source": {
               "contact_id": 12094631113617
            }
         },
         ...
         {
            "_index": "events_production_2015_04",
            "_type": "contact",
            "_id": "12094629244489",
            "_score": 1,
            "_source": {
               "contact_id": 12094629244489
            }
         }
      ]
   },
   "aggregations": {
      "contact_ids": {
         "doc_count_error_upper_bound": 0,
         "sum_other_doc_count": 0,
         "buckets": []
      }
   }
}

```

Then I do:

```
curl -XPOST 'http://cluster.host:9200/_cache/clear' -d '{ "fielddata": "true" }'

```

And just after that I do the same query and get the following result:

```
{
   "took": 2776,
   "timed_out": false,
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },
   "hits": {
      "total": 3614639,
      "max_score": 1,
      "hits": [
         {
            "_index": "events_production_2015_04",
            "_type": "contact",
            "_id": "12094631113617",
            "_score": 1,
            "_source": {
               "contact_id": 12094631113617
            }
         },
         ...
         {
            "_index": "events_production_2015_04",
            "_type": "contact",
            "_id": "12094629244489",
            "_score": 1,
            "_source": {
               "contact_id": 12094629244489
            }
         }
      ]
   },
   "aggregations": {
      "contact_ids": {
         "doc_count_error_upper_bound": 5,
         "sum_other_doc_count": 3614629,
         "buckets": [
            {
               "key": 5497558141098,
               "doc_count": 1
            },
            ...
            {
               "key": 5497558191959,
               "doc_count": 1
            }
         ]
      }
   }
}

```

I don't get any CircuitBreakingException exceptions at all. I checked all the nodes log files, and query response does not return any exceptions as well.
