英文:
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。
PUT my-index-000001
{
"_mappings": {
"_meta": {
"date": "2023-05-17",
"time": "10:12",
"author": "John Doe",
"scope": "Development"
}
}
}
可以使用更新映射 API 在现有类型上更新 _meta 字段：
PUT my-index-000001/_mapping
{
"_meta": {
"date": "2023-05-18",
"time": "23:10",
"author": "Jane Doe",
"scope": "Quality"
}
}
英文:
You can use the _meta field in the mapping to add any custom information that suits your index.
PUT my-index-000001
{
"mappings": {
"_meta": {
"date": "2023-05-17",
"time": "10:12",
"author": "John Doe",
"scope": "Development"
}
}
}
The _meta field can be updated on an existing type using the update mapping API:
PUT my-index-000001/_mapping
{
"_meta": {
"date": "2023-05-18",
"time": "23:10",
"author": "Jane Doe",
"scope": "Quality"
}
}
