When I start typing a phone number no suggested contacts from the contact list are shown

Question

Hello,

When I start typing a phone number there is no indication of which contacts match the already typed figures. This is a useful function available in other OSs (i.e. Android, Blackberry), making it easier to find a contact based on the first figures of the phone numbers and then choosing one of the contacts out of the suggested list .

¿Is there any option I haven't found or any application to install or it is an option not still available for WP 8.1?

Thanks!
