Re: Get the last entry from each of multiple types

[Jingzhao Ou]

Hi, David, 

Thanks a lot for your prompt help. I got both approaches working, which is 
very exciting. I prefer the top_hits aggregation approach. The msearch 
approach is not accepting normal JSON payloads, which makes things a bit 
harder for processing in Javascript. 

My query payload is shown below. Works like a champ! 

Best regards,
Jingzhao

{
    "size": 0,
    "query": {
        "bool": {
            "should": [ 
                { "term" : { "_type": "0000000000000001" } },
                { "term" : { "_type": "0000000000000002" } }
            ]
        }
    },
    "sort": {
        "id": "desc"
    },
    "aggs": {
        "top-tags": {
            "terms": {
                "field": "_type"
            },
            "aggs": {
                "top_tag_hits": {
                    "top_hits": { "size" : 1 }
                }
            }
        }
    }
}
