Set the refinable property to true for Managed Metadata Property in Search Service Application and do full crawl using PowerShell

Hi Again,

I came up with a requirement where I want to show the custom managed metadata property in the search refinement web part in the search results page.

By default the refinable property of any managed property is non set as false/not active. In order to show a property in the search refinement web part , it has to be active/true.

Below is the PowerShell script I wrote to update the custom managed metadata refinable property and then I did the full crawl.

	#Checking the Refiners refinable property for Managed Properties
	Write-Host "Checking for refinable property for managed property" -ForegroundColor Yellow
	$searchServiceApp=Get-SPEnterpriseSearchServiceApplication
	$isFullCrawlRequired=$false;
	#Custom Audience Managed Property
	Write-Host "Checking refinable property for CustomAudience" -ForegroundColor Yellow
	$audience= Get-SPEnterpriseSearchMetadataManagedProperty -SearchApplication $searchServiceApp | ? {$_.Name -eq "owstaxidCustomAudience"}
	#Metadata Managed Property is always starts with owstaxid*
	if($audience.Refinable -eq $false){
	$audience.Refinable =$true
	$audience.Update()
	$isFullCrawlRequired=$true
	}
	if($isFullCrawlRequired -eq $false )
	{
	$customContentsources=Get-SPEnterpriseSearchCrawlContentSource -SearchApplication $searchServiceApp | ? {$_.Name -eq 'YourContentSourceName'}
	if($customContentsources -ne $null)
	{
	Write-Host "Full crawl has started..." -ForegroundColor Yellow
	$customContentsources.StartFullCrawl()
	do {Start-Sleep -s 1} while ($customContentsources.CrawlStatus -ne "Idle")
	Write-Host "Full crawl is completed successfully..." -ForegroundColor Green
	}
	}
