Elasticsearch：[scroll] 中 VALUE_STRING 的未知键

Question

Elasticsearch scroll api 给了我这个错误

{
   "error": {
      "root_cause": [
         {
            "type": "parsing_exception",
            "reason": "Unknown key for a VALUE_STRING in [scroll].",
            "line": 2,
            "col": 15
         }
      ],
      "type": "parsing_exception",
      "reason": "Unknown key for a VALUE_STRING in [scroll].",
      "line": 2,
      "col": 15
   },
   "status": 400
}

我使用滚动 api 获取文档的代码是

GET index/type/_search?scroll=1m
{
    "size": 1000, 
   "query": {
      "match_all": {}
   }
}

这给了我很好的结果 "_scroll_id"

{
   "_scroll_id": "DnF1ZXJ5VGhlbkZldGNoBQAAAAAAAB1dFmJRbm9UR3h4UUFTVHFzV1dJMHpuOVEAAAAAAAAdXxZiUW5vVEd4eFFBU1Rxc1dXSTB6bjlRAAAAAAAAHV4WYlFub1RHeHhRQVNUcXNXV0kwem45UQAAAAAAAB1gFmJRbm9UR3h4UUFTVHFzV1dJMHpuOVEAAAAAAAAdYhZiUW5vVEd4eFFBU1Rxc1dXSTB6bjlR",
   "took": 37,
   "timed_out": false,
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },

现在根据文档我应该这样做

GET /_search
{
    "scroll": "1m",
    "scroll_id": "DnF1ZXJ5VGhlbkZldGNoBQAAAAAAAB1dFmJRbm9UR3h4UUFTVHFzV1dJMHpuOVEAAAAAAAAdXxZiUW5vVEd4eFFBU1Rxc1dXSTB6bjlRAAAAAAAAHV4WYlFub1RHeHhRQVNUcXNXV0kwem45UQAAAAAAAB1gFmJRbm9UR3h4UUFTVHFzV1dJMHpuOVEAAAAAAAAdYhZiUW5vVEd4eFFBU1Rxc1dXSTB6bjlR"
}

这给了我上述错误。我是否以错误的方式使用滚动 API？ES 版本为 5.5.1，kibana 版本为 5.5.1。我正在使用 kibana 访问 ES 服务器。

Answer 1

问题是我需要有

GET /_search/scroll
{
    "scroll": "1m",
    "scroll_id": "DnF1ZXJ5VGhlbkZldGNoBQAAAAAAAB1dFmJRbm9UR3h4UUFTVHFzV1dJMHpuOVEAAAAAAAAdXxZiUW5vVEd4eFFBU1Rxc1dXSTB6bjlRAAAAAAAAHV4WYlFub1RHeHhRQVNUcXNXV0kwem45UQAAAAAAAB1gFmJRbm9UR3h4UUFTVHFzV1dJMHpuOVEAAAAAAAAdYhZiUW5vVEd4eFFBU1Rxc1dXSTB6bjlR"
}

我忘了补充/scroll后_search。它现在有效
