Please suggest some inputs to restrict the field boosting to all rank profiles -- Fast serach for share point 2010 RRS feed

  • Question

  • Hi,

       We are facing a challenge while doing a field boosting by creating new rank profile in Fast serach for share point 2010.

    Once the field is boosted in to a custom created rank profile it reflects boosted in all rank profiles including the default one.

    Observation: Sorting of results in search center site doesn't change when we select different rankprofile in "site action link" webpart.

    Please suggest some inputs to restrict the boosting to all rank profiles.


    With Regards,

  • Can you please post the powershell that you used to create the custom rankprofile?

  • Please find the below commands for creating a custom rank profile and boosting a field "text" to it. But problem arises once the custom rank profile is made default. All boosted field to custom rank profile also reflects boosted in all custom and default profiles already exists in the index profile.

    Rp= New-FASTSearchMetadataRankProfile -name <NewRankProfile>


    $fp = Get-FASTSearchMetadataManagedProperty -Name fileextension

    $rp = Get-FASTSearchMetadataRankProfile -Name <RankProfile>

    $rp.CreateManagedPropertyBoostComponent($fp, "text,200000")



    Please help.........

  • In the example above you only create one rank profile <RankProfile>. Missing '$' in the first two lines, and missing one update(). Try listing your current rank profile to verify that the one you modify is not the default one.

  • We are even facing issues while boosting fields by creating a new rank profile and feild boosting doesn't reflect in the front end.

    PowerShell Command:

    $np = Get-FASTSearchMetadataRankProfile -Name default

    $np = New-FASTSearchMetadataRankProfile -Name testprofile -Template $rp


    $np.FreshnessWeight =400 (ALSO TRIED WITHOUT FRESHNESS WEIGHT)



    $np= Get-FASTSearchMetadataRankProfile -name testprofile


    $fileext = Get-FASTSearchMetadataManagedProperty -Name tranfer

    $np.CreateManagedPropertyBoostComponent($fileext, "text,1500900")


    $np.StopWordThreshold = 1000000


    Note: Also tried with “stop word threshold” & “position stop word threshold” by setting the value as 0

    Please suggest some help.......
