You cannot search existing keywords when there is no internet connection. Imagine you sit in a beer garden and want to show pictures to your friends and it is not possible. Or sitting in the airplane and want to search a picture, again, not possible. OK, the new advanced autodetect scenes need internet, but there are still normal keywords and descriptions in my pictures. You can test the issue with switching to airplane mode and touch on search symbol. Then the message appear that no search is possible. .
