In Plex, you can create Smart Playlists of music, movies, and videos, and smart “albums” for photos (Photo Albums used to be called “Playlists” as well, but that’s a whole 'nuther discussion).
To create smart albums, you use the filters to specify what you want, then select “Add to album” to create a smart album based on your filters. Once that’s done, any new photos with tags matching your filters will automatically be added to the smart album.
You can use more than one filter if you use the Custom Filters feature. Here’s how:
Now, the Custom Filters only search your manually-added tags - it ignores the Autotags that Plex automatically applies, if you’ve enabled that feature. Why Autotags are not incorporated into the Custom Filters, I don’t know. It may just be something that hasn’t been implemented yet.
There have also been some issues with the Custom Filters, where certain operators weren’t working properly (“is not,” for example). I don’t know if those have been fixed at this time.
