Clustered Search Result & Microsoft

In a recent article titled: Microsoft—Faceted Search Coming Soon? at Information Today, Paula Hane highlights Microsoft Search Results Clustering site (SRC) where they experiment with on the fly clustering of search results and entity extraction. If I may my advise to Microsoft team to move ahead quickly and integrate this solution at least initially with Academic Live, stop being displaying just "search results" (Google Scholar does that too) but provide some insights of the results and refine tools for the users.

I wish that someone from Microsoft Academic Live team (or even Google Scholar team) would explains why they haven't introduced the clustering and entiy extraction tools into Academic Live or Google Scholar?
