MSDN Search update

MSDN team have changed the Search function.

From Sara

We're working on launching a new search engine.  No, it's not Goggle.  But, it is one that we're pretty excited about because it significantly improve relevancy, and it gives a foundation to build on moving forward.  Our previous engine was really moldy, and didn't really enable some of the things that we'd like to do moving forward.   So, go check it out, and of course, tell me what you think.
