I defined date field as doc\_values in the template like that:

"createDate":{  
"type":"date","doc\_values":true,"fielddata":{"format":"doc\_values"}  
}

but when I run this command:

[http://my.server.com:9200/\_stats/fielddata?level=indices&fields=\*&pretty](http://my.server.com:9200/_stats/fielddata?level=indices&fields=*&pretty)

I can still see the field data hold values:

"createDate" : {  
"memory\_size\_in\_bytes" : 8942084  
}

Any idea why this can happen ?

It seems you're defining doc\_values twice, why is that?

Also they only apply to fields that are not analysed, which you haven't specified.
