Wicus van den Berg and I stand by our comments. Without the ability to apply carefully constructed information architecture (content types, metadata, storage location/site, etc.) into the search then it remains little more than a clever Google or Bing search. You can make those as smart as you like and they are still only adequate at providing findability (there is even some mathematics that defines this); it is the context that brings the power of enterprise search and without that then most large organisations with sophisticated implementations of O365 will have to use teh search centre, with the impact that has on both the SharePoint Online infrastructure and the user experience.
I love what is being done for simple search, but this seems to be another case of dumbing down at the expense of power users. My observation is that every time this has been done with SharePoint to date there has had to be a U turn (metadata, dropping of the SharePoint name, etc. etc.).
We need, on behalf of the large clients we support, some clarity on the intentions, since the published roadmap has nothing to say on the subject.
