How to search using phone number in contact app

Hi,

I can search in contacts app using the name of the contact. It works.
When I search for a number, search returns empty.

Say, if I have a contact ABCDE with number 333 444 6677
When I search for CDE, app will display contact ABCDE. When I search for 444, it doesn't list the contact.

I am coming from Samsung S5 and I could search contact using name or number.

Thanks for your help.
