SharePoint 2010 does not show search results when consuming SharePoint 2013 Search Service Application

Symptoms

 

When we performing a search from a SharePoint 2010 farm which is consuming a SharePoint 2013 search service application, all users receive the error as follows

"Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator"

 

if we take look into ULS log we may find below error in ULS

 

"w3wp.exe (0x02D4) 0x1788 SharePoint Server Search Query dn0c High CoreResultsDatasourceView: Could not find location with internal name LocalSearchIndex"

 

Cause

The locationconfigurations property in the search service application proxy could be blank in the SharePoint 2013.

 

 

 
Resolution

we need to check if  locationconfigurations property is null. And to do that we need to take help from PowerShell. We can use below script for the same.

 

$Url = "http://siteurl"
$site = Get-SPSite $Url
$serviceContext = [Microsoft.SharePoint.SPServiceContext]::GetContext($site)
$searchProxy = [Microsoft.Office.Server.Search.Administration.SearchServiceApplicationProxy]::GetProxy($serviceContext)
$searchProxy.LocationConfigurations

If this returns blank or null , we can repopulate that using PowerShell as below

$ssa = Get-SPEnterpriseSearchServiceApplication "Search Service Application"

”$ssa.Status = "Disabled"

$ssa.Update()

$ssa.Provision() 

this will actually recreate the Out Of the box location configurations again in the SSA Admin DB.

We can confirm that again running first script and once it got confirmed , users will able to get the search results in SharePoint 2010
