title: Searching a contact without country code in mat input (angular)
body: <p>I am working on <code>matinput</code> in angular templates. I am using it for searching puposes inside a list. In list we have different customers with contact i.e. (country code)(phone-number) +92 3011111111. When I search for +92 301... It works fine. But when I replace <code>+92</code> with <code>0</code> (as per number format in our region) It returns me with no contact. Is there any way to replace <code>+92</code> or any other country code with <code>0</code>. Thanks in advance. Lemme know if more clarification is needed. (vote question up if its clear and fine so i can ask more questions when needed)</p>
