How to handle advanced search with dynamic filtering addition using angularjs?

Below is the form for advanced search:

I am able to create url and params for document sections but i am unable to think for a process to handle the "Add Property Restrictions" section as the property can be added till 5 times and it is dynamic in terms of end user.

Like Below:

So i want to handle it in AngularJS with addition/deletion and dynamic changes on the go and also to form the url (GET/POST) to send the whole data for searching to the API for backend.

Thanks in advance!
