多个索引的动态索引设置

你可以将 Index Settings 示例中显示的相同更改应用于具有一个请求的所有现有索引，甚至是其中的一部分：

PUT /*/_settings
{
  "index": {
    "indexing.slowlog.threshold.index.warn": "1s",
    "search.slowlog.threshold": {
      "fetch.warn": "500ms",
      "query.warn": "2s"
    }
  }
}

要么

PUT /_all/_settings
{
  "index": {
    "indexing.slowlog.threshold.index.warn": "1s",
    "search.slowlog.threshold": {
      "fetch.warn": "500ms",
      "query.warn": "2s"
    }
  }
}

要么

PUT /_settings
{
  "index": {
    "indexing.slowlog.threshold.index.warn": "1s",
    "search.slowlog.threshold": {
      "fetch.warn": "500ms",
      "query.warn": "2s"
    }
  }
}

如果你更喜欢选择性地执行此操作，那么你可以选择多个而不提供全部：

PUT /logstash-*,my_other_index,some-other-*/_settings
{
  "index": {
    "indexing.slowlog.threshold.index.warn": "1s",
    "search.slowlog.threshold": {
      "fetch.warn": "500ms",
      "query.warn": "2s"
    }
  }
}
