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