Answer 1

简单排序

        $json = '{
              "aggs": {
                "first_judge_time": {
                  "terms": {
                    "field": "first_judge_time",
                    "order": [
                      {
                        "_term": "desc"
                      }
                    ], 
                    "size": 12
                  }, 
                  "aggs": {}
                }
              }, 
              "size": 0
            }';
        $params = [
            'index' => 'xx_index',
            'type' => 'doc',
            'body' => $json
        ];
        $res = $this->esClient->search($params);
