I have been trying to find an easy way for Lightroom to show me all of the photos I have that do not have keywords. It has been frustrating trying to find a solution for this as all I have been able to find when searching forums and such are somewhat complicated methods involving creating smart collections for Lightroom Classic in 2016, and none of it looks anything like the latest version of cloud based Windows Lightroom in 2023.
I feel like I must be missing something, because when I want to search through all my photos that I have not placed in any albums, the solution is to simply type "not in any album" in the top search bar. This seems like a basic enough function that when clicking on the keyword drop down there should be included a "no keyword" filter.
