For some months I've been working on a whitepaper for TechNet which walks you through all of the steps to connect metadata in a document through a content type and up into Search -- basically giving you the complete lifecycle for a document from creation through retreival.  Last week it published to the site.  The title of the whitepaper is “Managing Enterprise Metadata with Content Types.”  Unfortunately, search still hasn't found it yet :(  However, if you want to see it you can find the landing/summary page at http://technet2.microsoft.com/Office/en-us/library/21dcf8aa-8a6e-4325-aa17-0188e491361c1033.mspx?mfr=true and the actual document at http://technet2.microsoft.com/Office/logredir.aspx?MODE=CT&CTT=ToExternal&target=http%3A%2F%2Fgo.microsoft.com%2Ffwlink%2F%3FLinkId%3D101604%26clcid%3D0x409&referrer=http%3A%2F%2Ftechnet2.microsoft.com%2FOffice%2Fen-us%2Flibrary%2F636eceef-5b68-4231-b7f9-ab1531454e6f1033.mspx&reldir=en-us%2Flibrary

Please let me know what you think of it.
