Reset the content index (SharePoint Server 2010)

Question

according to that technet article it is possible to reset manually the content index.

I was wondering if that task could be plan to run once a week for instance, automatically?

Answer 1

I could find no OOB way to do this in stsadm or PowerShell, so you could either write a server specific custom timer job that does this at pre-scheduled interval, or create a PowerShell cmdlet that is called using schedule on the server that runs the Search Service Application.

using Microsoft.Office.Server.Administration;
using Microsoft.Office.Server.Search.Administration;

public static void ResetContent()
{

            try
            {
                SearchContext searchContext = SearchContext.GetContext(ServerContext.Default);
                searchContext.Reset(true);
            }
            catch (Exception ex)
            {
                throw new InvalidOperationException("Unable to reset content index.", ex);
            }

}

Alternatively in PowerShell

$searchApp = Get-SPEnterpriseSearchServiceApplication -Identity “SearchAppName”                                                        

if($searchApp -ne $null) {

  $searchAppCtx = [Microsoft.Office.Server.Search.Administration.SearchContext]::GetContext($searchApp)

  $searchAppCtx.Reset($true)

}

Corey Roth also coded this functionality as a cmdlet in his SharePoint PowerShell Community Toolkit

Answer 2

didn't try, but you can try in powershell:

$searchapp = Get-SPEnterpriseSearchServiceApplication
$searchapp.Reset($true, $false)

then you can schedule the powershell command
