Search Contacts by Nickname, Custom ID or Practically Any Field

Currently in RingCentral phone app, contacts are searchable only by First Name, Last Name or Phone number. Contacts should be searchable by any populated field. We would appreciate if contacts were searchable by at least Nickname or a custom ID (example employee number or customer number), I'm sure this will be very helpful for other customers too.

RC - Please implement it asap.
