Hi, I'm new to using Elastisearch and I'm completely stuck on a query. I've actually written this query that returns different values for all the ingredients.

> ```
> {
> "query": { 
> "bool": { 
> "must": [ 
> { 
> "range": {
> "timestamp": {
> "lte" 1584436490917
> } 
> }
> },
> { 
> "bool": {
> "should": [ 
> {
> "term": {
> "name": "IngredientName1"
> }
> }, 
> {
> "term": { 
> "name": "IngredientName2"
> }
> }
> ]
> }
> }
> ]
> }
> }
> }
> 
> ```

I would like to complete it so that it only returns the last value of each ingredient.  
Is it possible ? How ?  
Thanks for reading.

I found a solution with aggregations top hits so i close the ticket !  
Solution :

```auto
"aggs": {
    "IngredientName": {
        "terms": {
            "field": "name",
            "size": 10
         },
        "aggs": {
            "last_one": {
                "top_hits": {
                    "sort": [{"timestamp": {"order": "desc"}}],
                    "_source": {
                        "includes": ["name", "timestamp", "meta.valueText"]
                    },
                    "size": 1
                }
            }
        }
    }
}

```
