Hi all,  
Trying to follow the example from [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic-templates.html#_time_series), I marked all of the fields as not indexed - but supposibly they should be aggregate-able.  
According to Kibana over the same fields, they are not.  
Looking into a solution, enabling [doc\_values](https://www.elastic.co/guide/en/elasticsearch/reference/current/doc-values.html) suppose to do it - but seems like it does not work, and the dynamic field created does not have the doc\_values enabled.

Meanwhile it seems I must enable indexing for all fields in order to aggregate.  
Is this a known issue ?  
I am working on ES 5.

Thanks in advance,  
Shushu

I just tried this using elasticsearch directly:

```
DELETE test
PUT test
{
   "settings": {
	  "number_of_replicas": 0,
	  "number_of_shards":1
   },
   "mappings": {
	  "test": {
				
		 "properties": {
			"longField": {
			   "type": "long",
				"index":false
			 }
		 }
	  }
   }
}
POST test/test
{
	"longField":12
}
GET test/_search
{
	"aggs":{
		"longs":{
			"sum":{
				"field":"longField"
			}
		}
	}
}

```

Elasticsearch correctly produces an aggregation because doc\_values are available (setting doc\_values explicitly to false in the mapping breaks this).  
I tried pointing Kibana at the same index and as you suggest it failed to recognise this as an aggregatable field. I suggest you raise this in the Kibana forum as that seems to be where the issue is.

OK there is an issue here with the metadata elasticsearch provides to Kibana to determine what is aggregatable. The api Kibana uses [1] currently only returns "isAggregatable" info on indexed fields.  
We'll take a closer look on how to address this but for now to work with Kibana it looks like the worka-around is you'll need indexed fields (with the baggage that incurs).
