Finding size of total documents in an index

Elastic Stack Elasticsearch
1

Hi,
I want to find the sum of the sizes of all the documents containing a specific field.
e.g. for an index .index-dec-6-2020
I want to get the sum of the size of all the documents containing the filed delay: 5

Can someone point me towards a similar example or documentation?
Thanks

@dadoonet thanks for the reply. Actually I;m using elasticsearch in openshift environment (Logging Operator). Is there doc available for that? or any other way I can get the size?

I don't think there's unless you compute yourself the size and index that value in the document at index time.
