I'm trying to implement sql below:  
`select format(date,'yyyy-MM-dd'), count(*) group by format(date,'yyyy-MM-dd')`  
using RestHighLevelClient  
java code:

```auto
    SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
    sourceBuilder.query(QueryBuilders.matchAllQuery());
    sourceBuilder.aggregation(AggregationBuilders.terms("date_count").field("time").format("yyyy-MM-dd"));
    SearchRequest searchRequest = new SearchRequest("order_*");
    searchRequest.source(sourceBuilder);
    SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
    Aggregations aggregations = searchResponse.getAggregations();

```

I got the result but with many repeat date results as images shows below:

 ![{B140B0D7-EA44-40D3-BA65-AC88CFA0F11E}_20200317160043](https://us1.discourse-cdn.com/elastic/original/3X/c/2/c2b12b5ca0b18e6479c7441c1fbcf0578c27dc70.jpeg)

How should I avoid repeat date? I mean the same date(such as 2020-03-05) count as one row.
