For example , I want to insert new document which consist of two strings into myindex/mytype  
{  
"name" : "joe",  
"city": "ny"  
}

BUT mytype consist only of one string field : "name"

in this case I want the indexing to fail, and that elasticsearch return an error. How do I do that ?  
Right now it creates new document ☹

Thanls for your help !
