Nested field with script_field in a terms facet

Elastic Stack Elasticsearch
1

Hi everyone.

I stumbled upon an error and I am wondering if that's normal.
I try to run a terms facet with a script_field that looks like this :
"_source.myField".
When myField isn't nested, all's well. I get my results.
But when it is nested, i'm getting a error saying I can't access to that
field. Setting the nested property on the facet doesn't change anything in
that regard.

So, is it possible to use a nested field in such a script?
Thanks for any info !

It works for me. I suggest gisting a curl recreation of the problem, so
that we can see exactly what it is you are doing.

Hey Clinton,

Please have a look at the example curl found here:

I too am experiencing the same thing. Any ideas what we might be doing
wrong that you seem to be doing differently?

Thanks!

Hi Bob,

The _source is stored with the main (root) document and isn't accessible
from a nested inner object (it is decoupled from the main Lucene document
that has the _source). What you can do is store the chapter. paragraph.keywords field via the mapping (store=true) and access it via
the _fields['chapter.paragraph.keywords'] notation in the script.
