"order" question

Elastic Stack Elasticsearch
1

Hello. I would like to ask you something about the text on the official website below.

GET /my-index-000001/_search
{
  "sort" : [
    { "post_date" : {"order" : "asc", "format": "strict_date_optional_time_nanos"}},
    "user",
    { "name" : "desc" },
    { "age" : "desc" },
    "_score"
  ],
  "query" : {
    "term" : { "user" : "kimchy" }
  }
}

If "user" is left alone in this document, will it become "desc"? or will it be "asc"?
Does "order" in "post_date" make "user" decide?"
Please tell me the reason.

Also, I know that you can use "mode", "missing", and "unmapped_type" in addition to "order". Is there anything else?

Please let me know if there is anything other than "order".

Hi @kimjinyoung

Documentation:
The order defaults to descwhen sorting on the_score, and defaults to asc when sorting on anything else.

Does that mean that the current "user" is not specified, so it will be desc?

4

will be asc.

@RabBit_BR
Is "asc" because "user" is not specified?
Does that mean that "user" becomes "desc" when {"user":{"order"}}?

6

because order not specific.

and defaults to asc when sorting on anything else

just like that { "user": { "order": "desc" } }
