```Execute the following command also

FrontEndExecute[{HelpBrowserLookup["RegGuide", "Maximize"]}]

and see the "Furter Examples".

For your needs the following will give you waht you want.

(Minimize[(x + 0)^2 + (y - 2)^2, y == x^2 + 1 && #1[x, 0], {x, y}]
& ) /@ {Greater, Less}

{{3/4, {x -> 1/Sqrt, y -> 3/2}}, {3/4, {x -> -(1/Sqrt), y ->
3/2}}}
