创建搜索元数据映射
$searchapp=Get-SPEnterpriseSearchServiceApplication
New-SPEnterpriseSearchMetadataManagedProperty -SearchApplication $searchapp -Name mei -Type 2 -Description "苏梅华"
$mei = Get-SPEnterpriseSearchMetadataManagedProperty -SearchApplication $searchapp -Identity mei
$cmei=Get-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $searchapp -Name Return.Series
$cmei1=Get-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $searchapp -Name Return.Subscribes
New-SPEnterpriseSearchMetadataMapping -SearchApplication $searchapp -CrawledProperty $cmei -ManagedProperty $mei
New-SPEnterpriseSearchMetadataMapping -SearchApplication $searchapp -CrawledProperty $cmei1 -ManagedProperty $mei
效果图：
如果没有删除映射，删除元数据时会提示错误
删除搜索元数据：首先先删除搜索元数据映射
$PSSnapinSharePoin = Get-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction silentlycontinue
if( $PSSnapinSharePoin -eq $Null)
{
Add-PSSnapin Microsoft.SharePoint.PowerShell;
}
$searchapp = Get-SPEnterpriseSearchServiceApplication
$mp = Get-SPEnterpriseSearchMetadataManagedProperty -SearchApplication $searchapp -Identity su
$mapmei = Get-SPEnterpriseSearchMetadataMapping -SearchApplication $searchapp -ManagedProperty $mp
foreach($_ in $mapmei)
{
$prop = Get-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $searchapp -Name $_.CrawledPropertyName
$map = Get-SPEnterpriseSearchMetadataMapping -SearchApplication $searchapp -CrawledProperty $prop -ManagedProperty $mp
$map | Remove-SPEnterpriseSearchMetadataMapping
}
$mp | Remove-SPEnterpriseSearchMetadataManagedProperty
