I have a Json field called UserId in each document. I would like to create a new field that contains only the email domain.

Example:  
{ "FirstName" : "John", "LastName" : "Smith", "Email" : "jsmith@gmail.com" }

How do I create an analyzer and a copy\_to field that will let me have an additional field: EmailDomain : "[gmail.com](http://gmail.com)"

I know that the tokenizer will be the @ char, but I don't know how to create the analyzer, etc to do the rest of this.

Thank you!
