Excluding fields from results

Elastic Stack Elasticsearch
1

Hi there,

I just checked the docs, and it is possible to include only some
fields in the response instead of the whole _source variable. See
http://www.elasticsearch.org/guide/reference/api/search/fields.html

I'd like to do it vice versa: Is it possible to exclude certain fields
instead of including?

And the next thing which wonders me is the fact, that a new JSON
variable is created instead of _source called fields. Do I have any
influence on this name? I'd like not to change the frontend code
relying on the structure of the JSON :slight_smile:

Thanks for helping and have a nice day!

No, you can't exclude fields, and you can't change the names.

And can we use the mapping in order to obtain the same result? instead of exclude in query time exclude in indexing time?

Thanks
