Every time I try something like this:

doc['\_id'] + "/" + doc['site\_code'].value  
doc['\_index'] + "/" + doc['site\_code'].value  
ctx.\_index + "/" + doc['site\_code'].value

All shards crash???

Not very friendly. I'm trying a scripted filed via Kibana with latest hosting plan.

Hi @Tal_Weiss, I moved your post to `elasticsearch` category as I think that it can get a better answer here.

Thanks,
