How to I see all my unnamed faces in High Sierra?

I am using a smart album with these rules -assuming that the name of a person will include at least one vowel:

This album will show all photos with no named persons, but also include all photos without any persons at all.

I restrict this album to a date range as well, so I can search the most recently imported photos.

It is too late now for you, since et the names faces have vanished from your library. While I have been using El Capitan, where named faces did not sync at all between my devices with iCloud Photo Library I got into the habit to assign a keyword with the name of a person to all named people, in addition to using the Faces tags. The keywords synced between devices. And they are very stable and will survive, when the faces recognition algorithm gets updated.

have over 40K pictures and holiday gifts to work on where I need to look people up. I am so ****** they took that function away. Again, I appreciate your help.

Didn't you say that you want to name your recent photos? then add a rule to the smart album with "date added is after ....".

Thank you. Just got off the phone with Apple and they said the engineers took that option away...so I sent in feedback.

Yes, I thought it is intentional, because the engineers took another essential feature away - the ability to reject faces of strangers or items, that are no face at all by clicking the tiny x on the faces circle. The previous album of unnamed faces if not of much use, if we always have to wade of thousands of photos of strangers and statues or other artwork, when searching for the faces of the people we want to name. It would be like searching a needle in a haystack. Before the High Sierra upgrade the album of unnamed faces in my library had several thousand items that could not be removed other than giving each of them a separate name - stranger 1, stranger 2, statue 1, etc and then hiding these persons. It was hopeless after Apple removed the ability to remove faces of persons not relevant to us. Bringing back the "Unnamed" album will only make sense, if we also get back the ability to remove recognized faces of strangers, so they will no longer show in the "unnamed" album and overlayed on the photos.
