Looking at this page, it currently reads:
Search engine status: Not indexable
I think "Not indexable" is a bit misleading here. The page can still be indexed by search engines (including internal search engines), the page just happens to be marked in such a way that (external) search engines that opt to voluntarily follow the "noindex" directive will not publicly index the page.
Other software packages such as WordPress now use language such as "Search engines discouraged," which I think is more accurate.
