Does applying a tag to a folder not apply it to all items in the folder?

Hi,

I applied a tag to a folder, but when searching for videos with the tag, nothing comes up. Does applying a tag to a folder actually do anything?
And if so, is the only way to do something like this through a plugin like Mass Metadata Editor?
