Change the authority (anchor text) weight by using Windows PowerShell (FAST Search Server 2010 for SharePoint)

 

Applies to: FAST Search Server 2010

Note

When tuning dynamic rank, we recommend that you create a new rank profile, on which you can test the new component settings. For more on how to create new rank profiles, see Create and manage rank profiles by using Windows PowerShell (FAST Search Server 2010 for SharePoint).

1. Verify that you meet the following minimum requirements: You are a member of the FASTSearchAdministrators local group on the computer where FAST Search Server 2010 for SharePoint is installed.

2. On the Start menu, click All Programs.

3. Click Microsoft FAST Search Server 2010 for SharePoint.

4. Click Microsoft FAST Search Server 2010 for SharePoint shell.

5. At the Windows PowerShell command prompt, type the following command(s):

   $RankProfile = Get-FASTSearchMetadataRankProfile -Name <RankProfile>
   

   Where:

   • <RankProfile> is the name of the rank profile that you want to change the authority (anchor text) weight of. The default rank profile is named default.

6. Look at the current value:

   $RankProfile
   
   >> Name                                   :         default
   >> isDefault                              :         False  
   >> RankModelName                          :         default
   >> StopWordThreshold                      :         2000000
   >> PositionStopWordThreshold              :         20000000
   >> QualityWeight                          :         50
   >> AuthorityWeight                        :         80
   >> QueryAuthorityWeight                   :         50
   >> FreshnessWeight                        :         100
   >> FreshnessResolution                    :         Day
   >> FreshnessManagedPropertyReference      :         Write      
   

7. Change the authority (anchor text) weight:

   $RankProfile.AuthorityWeight = <AuthorityWeight>
   

   Where:

   • <AuthorityWeight> is the weight you want the parameter Authority to have relative to the other dynamic rank parameters, for example 1000.

8. Update the rank profile with the new values:

   $RankProfile.Update() 
   

9. Look at the rank profile to confirm that the new value is being used:

   $RankProfile
   
   >> Name                                   :         default
   >> isDefault                              :         False  
   >> RankModelName                          :         default
   >> StopWordThreshold                      :         2000000
   >> PositionStopWordThreshold              :         20000000
   >> QualityWeight                          :         50
   >> AuthorityWeight                        :         1000
   >> QueryAuthorityWeight                   :         50
   >> FreshnessWeight                        :         100
   >> FreshnessResolution                    :         Day
   >> FreshnessManagedPropertyReference      :         Write
