How to modify ES to create field default values?

Elastic Stack Elasticsearch

Hi Everyone.

I want to know how to modify the default value of the ES creation field?
For example:
I'm going to insert a piece of data.
Add the dizhi field, the default type is text, the participle.

I want to add the dizhi field, the default type is keyword, no participle
I hope to get some solutions. Thank you very much.

use mapping to update is.

Can the default part of the keyword type be inserted by default by configuration modification? How do you do it?

Change your mapping.

....
"dizhi" : {
  "type" : "keyword"
},
....

Note that this only can be set when creating a new index. You cannot change an existing index.
If you need to change existing data, you will have to reindex.

OK thank you
