Not all new crawled properties are automatically assigned a managed property mapping and made available for searching. If the MapToContents property on the category is set to $false, all new crawled properties discovered for that category will not be mapped into the default full-text index and made available for searching. Use the following procedure to look up unmapped and potentially new crawled properties.

  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 to display all categories:

    >> CrawledPropertyCount      DiscoverNewProperties      MapToContents   Name
    >>                  133      True                       True            SharePoint
    >>                   15      True                       True            Mail
    >>                   25      True                       True            Office
    >>                   54      True                       True            Basic
    >>                   52      True                       True            Web
    >>                   15      True                       True            OutsideIn
    >>                   10      False                      False           MESG Lingustics
    >>                   10      True                       False           Enterprise Crawler
    >>                    3      False                      False           Format Information
    >>                    7      True                       False           Managed Metadata
    >>                    0      True                       True            JDBC
    >>                   19      True                       True            Lotus Notes
    >>                    0      True                       False           People
    >>                    3      True                       False           Notes
    >>                    0      True                       True            Business Data
    >>                    1      False                      False           FAST Search Connector
  6. Get the category:

    $category = Get-FASTSearchMetadataCategory -Name "<CategoryName>"


    • <CategoryName> is the name of the category from which you want to display unmapped crawled properties, for example Notes.

  7. Get the list of unmapped crawled properties for the category:

    $unmappedCPs = $category.GetUnmappedCrawledProperties()
  8. Display the list:
