New-FASTSearchMetadataFullTextIndexMapping

FAST Search Server 2010
 

Applies to: SharePoint Server 2010

Topic Last Modified: 2010-03-04

Creates a new mapping from a managed property into the full text index.

New-FASTSearchMetadataFullTextIndexMapping -FullTextIndex <FullTextIndex> -Level <Int32> -ManagedProperty <ManagedProperty>

This cmdlet adds the content of a managed property to a full text index by mapping the managed property into the full text index. The mapping is only applicable to new content; existing content must be re-fed to appear in this full text index.

The managed properties are ordered by a concept called importance level. If the number of matching documents for a query term is greater than the StopWordThreshold for the rank profile in use, the Microsoft FAST Search Server 2010 for SharePoint system retries the query, limiting the managed properties searched to those from a higher importance level.

Importance level 1 (the first level that will be used in a query) includes managed properties from all levels 1 and up. Importance level 2 includes levels 2 and up. The maximum level is 7.

This process is called drilling. See Set-FASTSearchMetadataRankProfile for more information about StopWordThreshold.

 

Parameter Required Type Description

FullTextIndex

Required

Microsoft.SharePoint.Search.Extended.Administration.Schema.FullTextIndex

The full text index to add the mapping to.

Level

Required

System.Int32

The importance level of this managed property. Allowed values are 1 through 7.

ManagedProperty

Required

Microsoft.SharePoint.Search.Extended.Administration.Schema.ManagedProperty

The managed property being mapped to the full text index.

---------------EXAMPLE 1-----------------

$title = Get-FASTSearchMetadataManagedProperty -name title
$fulltextindex = Get-FASTSearchMetadataFullTextIndex -Name thirdfulltextindex
New-FASTSearchMetadataFullTextIndexMapping -ManagedProperty $title -FullTextIndex $fulltextindex -Level 3

This example maps the managed property called “title” into the full text index named “thirdfulltextindex” at level 3.

After this mapping is made, the content must be re-fed to populate the full text index.
