How to use store comma separated values in elastic search column?

I have comma separated values in one column and i want to use that column in elastic search.
Mapping created with Nested type.

Below is mapping :

"mapping": {
"doctype": {
"type": "nested",
"properties": {
"d": {
"type": "short"

After created index and Inserted data, i found some warning with that column.


So i want to know is there any issue with mapping? or it will create any issue in future? or is there best way to store this type of values?
