This issue happens because of the Symbolic Links. Symbolic links are the links to registry for each languague. When you are uninstalling or removing any software or role in the server, there will be chances that these links will also be removed. Reinstalling the Symbolic links can resolve the issue.

Steps to fix this issue:

1) Download the script Repair-ExchangeSearchSymlinks.ps1 from the below link:
http://gallery.technet.microsoft.com/scriptcenter/16afe88b-6c6d-49a3-8b03-2a2ece27f61a

Below is the script and can be saved in .ps1 format:
======================

write-host "Attempting to repair symbolic links" 
 
write-host "Stopping msftesql-exchange and msexchangesearch services" 
stop-service -Force msexchangesearch 
stop-service -Force msftesql-exchange 
 
$rval = get-PSSnapin -Name Microsoft.Exchange.Management.PowerShell.Setup -ea SilentlyContinue 
if(!$rval) 
{ 
    add-PSSnapin -Name Microsoft.Exchange.Management.PowerShell.Setup -ea SilentlyContinue 
} 
 
write-host "Installing symbolic links" 
Install-ContentIndexingService –HubOnlyFilterRegistration 
 
if(!$rval) 
{ 
    Remove-PSSnapin -Name Microsoft.Exchange.Management.PowerShell.Setup -ea SilentlyContinue 
} 
 
write-host "Starting msftesql-exchange and msexchangesearch services" 
start-service msexchangesearch 
start-service msftesql-exchange 
 
write-host "Symbolic links restored." 
write-host "Please run test-exchangesearch to verify installation."

======================== 

2) Copy the Repair-ExchangeSearchSymlinks.ps1 script to the Scripts directory on the Mailbox server (default installation is C:\Program Files\Microsoft\Exchange Server\v14\Scripts).
3) On the afflicted Mailbox server, open the Exchange Management Shell by right-clicking and selecting “Run as Administrator”.
4) Within the Exchange Management Shell(EMS), navigate to the Exchange Scripts directory.
5) Within the Exchange Management Shell, run the following script:
.\Repair-ExchangeSearchSymlinks.ps1
6) Now reset the index file by issuing the below command within the EMS:
.\ResetSearchIndex.ps1 -All  (this is for all databases in the server)

If you want to reset on particular database then:
.\ResetSearchIndex.ps1 -(database name)

Wait for few hours for the indexing to rebuild on the server. If the issue still exists, try to restart the server or Information store service.
