I have setup a smart collection of flagged photos inside a collection set that for simplicity I'll call Collection 1. When I setup the smart collection to view flagged items in this set it returns 0 even though there are hundreds. If I change the criteria to a folder called the same name it will find the photos. When choosing a source it only shows Folder or Collection. Can I make look for items in a collection set?
I'm not 100% sure of your intent, but I believe smart collections cannot use a collection SET as a source. I believe you'd have to name the collections within.
Lame, for sure. Complain to Adobe so they'll add it.
Thanks, I was starting to think that was the problem and makes the whole concept a little less useful.
It's not easy to apply smart collections to particular sources (folders, collections, collection sets). See this post for workarounds: Lightroom: Limit Smart Collections to a Collection or Collection Set | Photoshop Family Customer Community. Also, add your vote and opinion to that topic, which is in the official Adobe feedback forum. Adobe product developers actively participate in that forum, rarely so in this forum.
