Comment 5 for bug 780841

@Harry: The folders don't always show up for me because my unity search results for the same query are often inconsistent (see bug 810823). Are you seeing a Files & Folders section at all (what if you create a file called ~/downloads.txt)?

Here's more formal steps.

Load up a natty LiveCD
Search "down" and get the Downloads folder
Delete the ~/Downloads folder from nautilus
Search "doc" (workaround bug 810823)
Search "down" and the Downloads folder is still there!

You shouldn't have to do anything other than delete a folder from nautilus to make it stop showing in your results. That's how it works for any other file.

I tried applying updates to the LiveCD, but I don't have enough memory. However, I've updated unity (dpkg -l output changes from 3.8.10-0ubuntu2 to 3.8.16-0ubuntu1-natty1) and run setsid unity to restart unity. The above steps still show the Downloads folder.
