We should consider adding a standard help link to Special:MediaSearch that points to the feature's docs on mediawiki.org, like this:
I would also recommend we consider moving the docs from Help:CirrusSearch/MediaSearch to Help:MediaSearch. With the current URL, you can't easily get to the help page via the search bar and it won't be the first search result unless you get the casing right. Plus, the Help:CirrusSearch page does not link to the MediaSearch page, so it seems pointless to include it as a subpage.
