Scripted partial delete

Elastic Stack Elasticsearch
1

Hi

I want to delete just one element from a list
Is that possible inside a script?

From the docs it only appears possible to delete the document if it
contains an element.

The solution then I guess is to read the entire document. And delete in
memory the relevant piece.

Then write back the remainder?

But I was hoping for a "bulk" based approach

Thanks,

Actually it is possible!
It's a mvel thing

In mvel it's possible to
_source.doc.list.remove (elem)

The options in elasticsearch documentation do not go very deep.

Maybe another discussion group for mvel scripting questions ?
