I have an index that looks like this:

{  
"id":1,  
"countries":["china","japan","united states"]  
},  
{  
"id":2,  
"countries":["china","united states"]  
}

I want an output like this:

{ china: 2 }{ united states: 2} { japan: 1}

Is there a query or aggregation that does this?

I found it. I need the terms aggregator.

```auto
curl -XPOST 'localhost:9200/someindex/_search?size=0&pretty' -H 'Content-Type: application/json' -d'
{
    
    "aggs" : {
        "countries" : {
            "terms" : { "field" : "countries" }
        }
    }

}
'

```
