No I do not tag people but that doesn't matter as the new Google people search can be done without tagging.
I thought you were talking about photos you already had indexed, it does not pick up all the faces in a general search. I tested it and it does not pick up all the faces. I have quite a few photos that it skipped.
Any resolution to this ? I'm in the U.S. and I have "group similar faces" turned on under settings.
I cannot search even the most basic items (cars, dogs, snow, etc.). I have no specific choices that some up to search for things or people. Only one search bar. All results are returned with "No results found".
