Is it possible to update the whole index using a script? Let me give an  
example:

on my curent index I have a mapping:

{  
"name" : "string"  
}

I'd like to include an extra field on every document, called auto\_complete,  
and have the name field stored there, but using a different analyzer  
(EdgeNGram for instance), so I can change the mapping, and later run a  
single script to do that.

I know I could just go over the api and do doc by doc, just trying to  
understand if there's an easier way around.

Regards

No, there isn't an option to do that in elasticsearch itself. You probably  
are better off simply reindexing the data (from the existing index for  
example), or simply taking into account that some docs will have that field  
missing.
