Is filter noun or verb?
It's a verb. However I have authored a change to the message to make it even easier to grasp. This should roll in these days. Thank you for your patience!
Edit: Ouch. Disregard the change. I have updated and improved the message documentation to convey the messages' meaning better. --[[kgh]] (talk) 16:37, 14 February 2014 (UTC)
