Can we update the response in curl (GET) query that, if the field datatype is string or date or integer and we get the value as null or other then change it to 'Some other text'.  
For example  
if i have a string field in ES and the value is '123' can we parse it to integer using curl query?

That is not possible with Elasticsearch.
