I want to add a new field to a document with document\_id like "{id}-{word}" by using logstash.  
I just know {id} part while updating. Is there a way can I do it either by update\_by\_query in script and how should I define document\_id in elasticsearch output plugin.

I'm trying to do:  
elasticsearch {  
index =\> "ib-node\_parsed-v1"  
document\_type =\> "parsed\_node"  
document\_id =\> {  
#not sure about this part, is there any way to achieve this. I want to do "Update all documents where document\_id is like {456789}-{word}  
grok {  
match =\> { "message" =\> "event.get('uniqueCollectionId')-%{GREEDYDATA}"  
} }  
action =\> "update"  
hosts =\> "ip:9200"  
script\_lang =\> "painless"  
script\_type =\> "inline"  
script =\> '  
ctx.\_source.brandingName = params.event.get("brandingName");  
ctx.\_source.globalCustomerId = params.event.get("globalCustomerId");  
'  
}
