Actually, I think here the default -- to have the More Information group 
closed -- is quite reasonable. So that what you see is the brief 
Information output cell near the top and the EXAMPLES group initially open.

I've spent a lot of time watching Mathematica beginners learn, and 
there's no question that most of them instinctively head first for 
examples and only afterward (if at all) looking for an actual description.

If you want to open all the closed groups in _any_ window, including a 
window inside the Help Browser, after being sure that window has the 
focus, you can do it with the menu:

   Edit > Select All
   Cell > Grouping > Open All Subgroups

And the menu items will show you which keyboard shortcuts to use on your 
platform.
