Re: Update API - how to remove inner fields from objects via script?

[Steve Flook]

Nevermind folks thanks anyway.  I took a look at the ES source.  Each 
object in the doc has it's own methods such as remove():

POST 
/test-timbr-2015.02.19/event/0f78c6b6-a30b-436e-bad7-4234654fc5bb/_update
{
"script" : "ctx._source.realm.remove(\"name \")"
}

Update API - how to remove inner fields from objects via script?

[Steve Flook]

I have an index that supports dynamic mappings under a field of type Object 
that we named custom.  My doc also has other objects properties with inner 
props.  I attached an abbreviated mapping - notice my object for "realm" 
and it's properties

Using the Update API I can remove a field per the docs 

 
*if* it's a top level field.  For example this works great:

POST 
/test-timbr-2015.02.19/event/0f78c6b6-a30b-436e-bad7-4234654fc5bb/_update
{
"script" : "ctx._source.remove(\"threadid\")"
}

However, when I run the script against a document that has a field nested 
in a specific object graph the specified field doesn't get deleted.  I'm 
using dot notation as you can see, and when I run this ES comes back with a 
HTTP 200 and the _version property gets incremented.

POST 
/test-timbr-2015.02.19/event/0f78c6b6-a30b-436e-bad7-4234654fc5bb/_update
{
"script" : "ctx._source.remove(\"realm.name\")"
}

How can I get inner properties like this removed via the Update API.

Thanks for your help.
Steve
