In SharePoint 2010 Search, I've added a new managed property that refers to a lookup column. I then added a custom refiner by modifying the Refinement Panel "Filter Category Definition". Basically, I followed the steps in this article: http://blogs.msdn.com/b/spnext/archive/2010/08/09/customising-sharepoint-2010-search-refiners.aspx.
The refinement is working just fine except the refiners appear with the lookup ID and the lookup text. Is there anyway to just display the text?
