Hastags working improperly when a discussion also has tags in it

[jwidness]

When I try to build a collection, it seems that if a video has a discussion going that has hashtags in it, those are the only tags the collection looks at. For example, when I built a collection looking for #mangabey, but excluding #lingeringshape, ACP0005xbw was incorrectly in that collection. When I added the #lingeringshape tag to the discussion, it then was correctly not in that collection.

I think I was slightly wrong -- sometimes the tag has to been in both the comments and the discussion, but I haven't really figured out when...

Ok, I think I've got it. It seems like the way it works is that when you create a collection, it independently evaluates the comments and the discussions, and if either one alone says to add that video, then the video gets added. So an example case that behaves in a way that I wouldn't expect is if you put tag1 in the comments, and tag2 in the discussion, and then ask for videos with tag1 AND tag2. Here it fails to get the video. There are even more fail cases when you use exclude.
I would expect the behavior to be: first create a union of all the tags that exist in either the comments or discussions, then evaluate the collection criteria.
