This isn't something you see every day and that's the only reason I took the screen grab - here we see AltaVista results ranking on the first page in Google.
Google's said (via Matt Cutts) that it doesn't want other search results ranking in the index. They took action to remove YouTube search results out. This may be why UK charity search engine Everyclick struggles to rank even on non-search pages. It is also a statement that gives retailers with faceted search CMS sites cause for concern although Google's not likely to treat those canned search/navigation pages the same as 'free hand' search results.
