This topic explains how to work with crawled properties in Microsoft FAST Search Server 2010 for SharePoint by using Windows PowerShell.

In this section:

  • Configure category to discover new crawled properties by using Windows PowerShell

  • Re-order crawled properties mappings by using Windows PowerShell

  • Look up a crawled property if you know the full name of the property by using Windows PowerShell

  • Look up a crawled property if you know part of the name of the property by using Windows PowerShell

  • Look up all crawled properties in a category by using Windows PowerShell

  • Map a crawled property to a managed property by using Windows PowerShell

Configure category to discover new crawled properties by using Windows PowerShell

Crawled properties are automatically extracted from crawled content and grouped by category based on the property-set of each crawled property. Each category can be configured individually to discover new crawled properties, or not.

  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):

    Set-FASTSearchMetadataCategory -Name "<CategoryName>" -DiscoverNewProperties "<Flag>"

    Where:

    • <CategoryName> is the name of the category to update.

    • <Flag> is a Boolean indicating whether or not new crawled properties should be discovered for this category. Use $true if crawled properties should be discovered, $false if not.

If a crawled property is discovered and it has a property-set that is not mapped to an existing category, a new category will be created for the property-set as well as the new crawled property. The new category will be named Category # (where # is a category number).

#Get the crawled properties to be stored in position 1 and position 2:
$cp1 = Get-FASTSearchMetadataCrawledProperty -Name "<CrawledPropertyName1>"
$cp2 = Get-FASTSearchMetadataCrawledProperty -Name "<CrawledPropertyName2>"
#Remove the properties from their current position in the list:
$mappings.Remove($cp1)
$mappings.Remove($cp2)
#Insert the crawled properties in their new positions:
$mappings.Insert(0, $cp1)
$mappings.Insert(1, $cp2)
#Call SetCrawledPropertyMappings(...) to make the update permanent:
