If you have to globally demote a type of document in your fast search results, you can do it via FS4SP powershell with a pretty cool function called “AddPromotedExpression”.
AddPromotedExpression takes in input your FQL expression applying it to all the query submitted in FAST.
Here the powershell lines:$SettingGroup = Get-FASTSearchSearchSettingGroup -name “GUID of the site collection that hosts your search center site ”
$GlobalPromotions = $SettingGroup.PromotionsWithoutKeyword $GlobalPromotion = $GlobalPromotions.AddPromotion(“DEMOTE BCS RESULTS”) $GlobalPromotion.BoostValue = “-4000” //DEBOOST
$fqlEx = ‘and(path:starts-with(“bdc3://”))’ //MY Business Connectivity Service RESULTS TO DEMOTE
SO NICE 🙂
