求问以下elastic search query要变成Java query builder怎么实现？

GET <index-name>/_search
{
  “size”: 1,
  “sort”: [
  {
    “Date”: {
    “order”: “desc”
   }
  }
 ]
}

感谢！

public SearchSourceBuilder build(){
        SearchSourceBuilder builder = new SearchSourceBuilder();
        BoolQueryBuilder query = QueryBuilders.boolQuery();
        builder.sort(new FieldSortBuilder("Date").order(SortOrder.DESC));
        builder.query(query);
        builder.size(1);
        return builder;
    }
