Returning some fields without _source, is it possible?

Elastic Stack Elasticsearch
1

Hi,
I know this has been asked a bunch and I see the answer regarding fetching
only some fields from a query.
However, my documents have thousands of dynamic fields. I cannot define
them in a mapping with "stored: True".
The documents are megabytes in size. I do not want elastic search returning
a 45MB _source result for each
and then pluck fields from there.

Is it possible to query and retrieve only a few fields from results? I do
not want _source....too big....

thanks!

Yes, it it possible:

You could also use the 'fields' parameter in the URL:
localhost:9200/index-name/type-name/id?pretty&fields=id,name
