Do we have any other instances where we link to external sites within search results, this seems slightly concerning to me.
And also OT for this list. :) But yes, there are plenty of instances of Special:Search sending users to other search engines if they choose so; content may not directly loaded except from Wikimedia servers for the (current) privacy policy (can't speak for the future one if any).
