Angular filter exactly on object key

Answer 1

Specify the key (property) of object in filter, on which you want to apply filter:

//Suppose Object
var users = [{
  "firstname": "RAM",
  "lastname": "KUMAR",
  "Address": "HOUSE NO-1, Example Street, Example Town"
  },
  {
  "firstname": "SHAM",
  "lastname": "RAJ K",
  "Address": "HOUSE NO-1, Example Street, Example Town"
}]

But you want to apply filter only on firstname
