Hi,
I have a problem with changing mapping of specified field. the field has
"index":"no" and I want to change it to "index":"analyzed". Putting new
mapping throws error. What should I do to apply new mapping for existing
data?
Best regards.

Sorry for mistake, I meant the other way, I want to change
from "index":"analyzed" to "index":"no" and add "include\_in\_all":false and
"store":"yes" 🙂

Summarizing, I want to do both ways :). I would really appreciate your help.
Thanks.

I'm afraid you have to clean your existing datas.
IMHO, you can merge mappings on new fields but you can't change "core"
mappings for existing datas.

Yea, you can't change an existing mapping "index" mapping, because it
requires reindexing the data. You need to do it yourself (the reindexing
part) into a fresh index with the updated mapping.

Using index aliasing is a big help for changes like this as the new index
can be created and then the alias changed when all is done. (+2c)
