Lightroom Web - Search - Multiple Lightrooms

It's not a Google-level search tool, and I wouldn't invest huge effort in it.

But it can be handy at times. What it will do is search for images by using:

1. any metadata synced with the files
2. AI-added tags

Metadata synced with the files includes stuff like title and caption, and any keywords saved to metadata before the photos were added to sync. Note the stress there - new keywords won't get synced and won't be searchable.

AI-added tags are completely behind the scenes. You can't see them, and you can't change them. But for example, I can search on Red and it'll find images with lots of red, even if I never added the colour as a keyword. It would also find images captioned with Red Bull Race, for example. Search for Dog and you'll probably get a few horses and cats too. It won't find text in photos, so it won't find pictures of posters containing the words Red Bull, and it won't recognise locations such as the Eiffel Tower. It would find pictures of it only using title, caption and any keywords, even though it is one of the most well-known objects in the world.

You can access this search from other computers through the web browser, and save the findings to new collections which will sync back to Classic.
