A smart collection uisng the criteria Collection and Publish Collection doesn't always update its results properly in LR 4.4 and LR 5 Beta (Windows 7 64-bit). Here's how to reproduce:
1. Create a Flickr publish collection named "test 1" with 1 photo. Create a collection named "test 2" with 2 different photos.
2. Define a smart collection named "Collection test" defined as "Match all", "Publish Collection contains test". Observe that it properly selects the 1 photo in the Flick publish collection "test 1".
3. Edit the smart collection to instead use the criterion "Collection contains test". Observe that it continues to select just the 1 photo in the publish collection "test 1", not the 2 photos in the collection "test 2".
Here's a screen shot:
