elasticsearch - 在 sense 上使用扫描和滚动进行 elasticSearch

Question

我正在尝试遍历 elasticSearch 中的多个文档，并使用 Sense(谷歌浏览器插件来执行此操作)。使用扫描和滚动来提高效率，我得到的滚动 ID 为:

POST _search?scroll=10m&search_type=scan
{
  "query": { "match_all": {}}
}

结果是:

{
   "_scroll_id": "c2Nhbjs1OzE4ODY6N[...]c5NTU0NTs=",
   "took": 10,
   "timed_out": false,
   "_shards": {
     "total": 5,
     "successful": 5,
     "failed": 0
  },
  "hits": {
     "total": 20000,
     "max_score": 0,
     "hits": []
  }
}

然后将其传递给 GET 为:

GET _search/scroll?scroll=1m&scroll_id="c2Nhbjs1OzE4ODY6N[...]c5NTU0NTs="

但我得到 0 个结果，特别是:

{
  "_index": "my_index",
  "_type": "_search",
  "_id": "scroll",
  "found": false
}

Answer 1

我发现了问题，我在服务器框中指定了索引my_index。删除它并重新执行 post 命令:

POST /my_index/_search?scroll=10m&search_type=scan
{
    "query": { "match_all": {}}
}

并将生成的 scroll_id 传递为:

GET _search/scroll?scroll=1m&scroll_id="c2Nhbjs1OzE4ODY6N[...]c5NTU0NTs="

成功了!
