How to comment on an Elasticsearch index mapping?

问题

There is no direct translation needed for code-related phrases. Here's the translation of the non-code part:

"在我创建一个供更大团队使用的索引时，我需要记录基本信息，如日期、时间、作者、范围等。

除了过于显眼的索引名称之外，是否有可以使用的注释字段？"

英文:

As I create an index used by a larger team, I need to document basics like the date, time, author, scope, etc.

Is there a comment field I can use besides the too-exposed index name?

你可以使用映射中的 _meta 字段 来添加适合你的索引的自定义信息。

  1. PUT my-index-000001
  2. {
  3.   "_mappings": {
  4.     "_meta": { 
  5.       "date": "2023-05-17",
  6.       "time": "10:12",
  7.       "author": "John Doe",
  8.       "scope": "Development"
  9.     }
  10.   }
  11. }

可以使用更新映射 API 在现有类型上更新 _meta 字段：

  1. PUT my-index-000001/_mapping
  2. {
  3.   "_meta": {
  4.     "date": "2023-05-18",
  5.     "time": "23:10",
  6.     "author": "Jane Doe",
  7.     "scope": "Quality"
  8.   }
  9. }
英文:

You can use the _meta field in the mapping to add any custom information that suits your index.

  1. PUT my-index-000001
  2. {
  3.   "mappings": {
  4.     "_meta": { 
  5.       "date": "2023-05-17",
  6.       "time": "10:12",
  7.       "author": "John Doe",
  8.       "scope": "Development"
  9.     }
  10.   }
  11. }

The _meta field can be updated on an existing type using the update mapping API:

  1. PUT my-index-000001/_mapping
  2. {
  3.   "_meta": {
  4.     "date": "2023-05-18",
  5.     "time": "23:10",
  6.     "author": "Jane Doe",
  7.     "scope": "Quality"
  8.   }
  9. }
