I have a FAST Search site collection and, in results.aspx, I'm trying to configure the 'Refinement Panel' web part so it displays my custom taxonomy which I've created in Managed MetaData service. If I edit this web part I can see in the "Filter Category Definition" the line:
<Category Title="Managed Metadata Columns" Description="Managed metadata of the documents" Type="Microsoft.Office.Server.Search.WebControls.TaxonomyFilterGenerator...>
So I guess the question is how to I go about refining the list of "Managed Metadata Columns". The weird thing is, depending on what I search for, the occasional custom metadata field does appear. But why does just that one term appear and not the rest? My documents in the search results have plenty of metadata values associated to it so that shouldn't be an issue.
I'm doing all this from the SP2010 Contoso virtual, Beta 2.
Any help would be appreciated.
