I have numerous photos in my lightroom cc catalogue.
however if I use a keyword search, I end up with some photos that don't have the keyword specified.
For example I tagged all my high res photos (I have some 600x400 previews) with 'hires' yet when I search, lightroom is returning me photos WITHOUT that keyword. This occurs even when using a single keyword in the search bar.
Lightroom CC uses cloud based artificial intelligence to search for images. Theoretically this eliminates the need for keywords. I’m not sure if there is a way to turn of the AI when searching. Here’s a page of tutorials on this subject. Maybe the answer is in one of these videos.
I'm currently having this same problem. I searched my photos for wedding and photos that don't have the term wedding anywhere are showing up in the results. Were you ever able to figure out how to fix this?
