As you may already know you know promote some link or document as best bet for a search results (Search keyword and Fast Search Keyword.

BUT, if your search center (SharePoint or Fast) is independent; meaning located in other web application (search search.hametbenoit.info), managed keyword will not be used for promoting your Best bet. Indeed, the scope for keywords is limited to the site collection.

When I wanted to implement this feature with my Fast environment, I discovered that the Fast Search feature were not available through the Site Settings (Site Actions\Site Settings\Site collection administration).

As there is no ‘manageable Fast features’ (meaning no link available through the Site Settings\Site collection features), I looked for enabling it using PowerShell (Get-SPFeature | Where {$_.DisplayName -like "*search*"})

As result

So, the Fast feature GUID is 5EAC763D-FBF5-4d6f-A76B-EDED7DD7B0A5.

Then to enable the feature on your site (this is also applicable for ‘non search center’ template site, in case of this feature is missing), open a PowerShell command and run

$site = get-SPSite <URL of your site collection>

$site.Features.Add(“5EAC763D-FBF5-4d6f-A76B-EDED7DD7B0A5″)

Et voilà, I was then able to add Fast keyword on my Fast search center.
