Elasticsearch 中的条件更新："Invalid op [none]"

Question

弹性搜索 2.3。我正在触发此查询以根据条件更新索引中的每个文档。

{
  "query": {
    "bool": {
      "must": [
        {
          "match_all": {}
        }
      ]
    }
  },
  "script": {
    "inline": "if (ctx._source.url.endsWith('a=6')) ctx.op = 'none' else ctx._source.url = ctx._source.url + '&b=3'"
  }
}

如 here 所述，我使用 ctx.op = 'none' 来避免更新不符合条件的文档。

我得到

Invalid op [none]

完整错误：

"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "Invalid op [none]"
}
],
"type": "illegal_argument_exception",
"reason": "Invalid op [none]"
},
"status": 400

好像很简单，看得我都懵了。感谢您的帮助。

正确的操作是noop，不是none。

来自the documentation：

Just as in Update API you can set ctx.op = "noop" if your script decides that it doesn’t have to make any changes. That will cause _update_by_query to omit that document from its updates.
