I have a SharePoint 2010 with FAST search installed. In the FAST Query SSA, I can find 2 places contain "Metadata properties":
- /searchadministration.aspx, under Queries and Results > Metadata properties
- /searchadministration.aspx, click FAST Search Administration (/_admin/search/extendedsearchadministration.aspx) > Managed Properties
My guess is I should use Managed Properties for my FAST Search customization, however when I try to add new properties and map to crawled properties, I found that some crawled properties only can be found in "Metadata properties" but not in "Managed Properties"
I have read this article about crawled properties http://searchunleashed.wordpress.com/2011/08/24/understanding-crawled-properties-managed-properties-and-full-text-index-part-1/ in my opinion, the crawled properties in both section should be the same.
Am I correct?
