Introducing a new resource for all role-based Microsoft Certification exams

I took AI-102 today. Learn was available. There were a couple of places where I found it helped, at least to confirm the purpose of a specific option, etc. 

What I do find hard with it though, is the searching for content. The search bar in Learn is not a good way to search Learn. If it was, this would work better. We're not going to get a Google search in there (i.e., what most people would actually use), but it would be interesting to have the option to use Bing search and enforce a site restriction for Learn. The other challenge would be to limit where you could link to from Learn. I didn't try any external links but I presume they have some sort of restriction on those). 

I also remember someone asking if there's a limit to the number of tabs you can have open. I found it refused to open more after about 5 (didn't note the exact number).
