Yes. TARK4 can be deployed as a standalone product that may be used with all content management and production systems via plugins, RSS feeds, e-mail, browsers and Web Services.
However, the tightest integration is, of course, achieved when TARK4 is paired with GN4.
TARK4 has the Exalead's CloudView search engine built in.
