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).
