It's been said mant times that MS changes things based on how they think it should work, but don't truly ask lots of users...and in most cases don't give you the option to do it differently.  Herding everyone into searching for everything rather than using the index is stupid.  Please give back the index.  What good does it do to remove something that wasn't hurting anyone in the first place.  The index is much easier for me to not only logically find things, but to see where they fit in the parent topic.  Why would a company who promotes thinking intelligently, guide people into a lack of thinking by just searching for everything.
