查询语句中一开始ranges没有key键，只有{“”from”: 0,”to”: 10”}，这样查询的结果会转成浮点数，如下
1 | {'buckets': [{'key': '0.0-10.0', 'from': 0.0, 'to': 10.0, 'doc_count': 0}, {'key': '10.0-20.0', 'from': 10.0, 'to': 20.0, 'doc_count': 0}, {'key': '21.0-30.0', 'from': 21.0, 'to': 30.0, 'doc_count': 1}, {'key': '31.0-40.0', 'from': 31.0, 'to': 40.0, 'doc_count': 4}, {'key': '41.0-50.0', 'from': 41.0, 'to': 50.0, 'doc_count': 5}, {'key': '51.0-60.0', 'from': 51.0, 'to': 60.0, 'doc_count': 16}, {'key': '61.0-70.0', 'from': 61.0, 'to': 70.0, 'doc_count': 29}, {'key': '71.0-80.0', 'from': 71.0, 'to': 80.0, 'doc_count': 12}, {'key': '80.0-90.0', 'from': 80.0, 'to': 90.0, 'doc_count': 3}, {'key': '91.0-100.0', 'from': 91.0, 'to': 100.0, 'doc_count': 0}]} |
加上key就可以指定返回的key了
