I had a customer where Exchange 2013 FAST Search Technology failed and rebuilding the search indexes for the databases did not resolve the problem on a single Exchange 2013 SP1 server.
In this blog post I'm going to share with you the symptoms of my issue along with the resolution.
Symptoms of Issues
Users on the network were unable to search their mailbox from Outlook Web App or using Microsoft Outlook in online mode.
In addition to not being able to search in Outlook Web App or Microsoft Outlook, the Test-ExchangeSearch cmdlet failed with "Time out for test thread".
Despite this issue, the ContentIndexState on the databases remained in a Healthy report status with the Get-MailboxDatabaseCopyStatus cmdlet as shown below:
In the Server Application logs the following error was logged numerous times:
Log Name: Application
Source: MSExchangeIS
Date: 4/12/2014 1:54:06 PM
Event ID: 1012
Task Category: General
Level: Error
Keywords: Classic
User: N/A
Computer: ExchangeServer.domain.local
Description:
Exchange Server Information Store has encountered an error while executing a full-text index query ("eDiscovery search query execution on database a0976351-948a-4625-8840-f649f8b98e0e failed."). Error information: System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://localhost:3847/. The connection attempt lasted for a time span of 00:00:02.0821592. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:3847. ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:3847
Checking the size of the catalog folder was only around 16MB when the database size was 150GB. From my experience a FAST index for a 150GB database is generally between 5GB and 10GB in size depending on how small the items are inside the database.
Issue Resolution
To resolve the issue the following steps were taken in order.
1. Stop the Microsoft Exchange Search and Microsoft Exchange Search Host Controller service.
2. Remove all the files under �Fsis� file:
C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\HostController\Data\Nodes\Fsis
We moved these files to another folder for backup purposes.
3. Open EMS and �Run as Administrator"
4. Navigate to directory C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Installer
5. Launch the script and run the command below:
.\installconfig.ps1 -action I -datafolder "c:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\HostController\Data"
This script will recreate the files under "C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\HostController\Data\Nodes\Fsis" that we backed up/removed previously.
6. Once the script installs the data, you need to uninstall and reinstall again (don't ask, it did not work for me without doing this):
.\installconfig.ps1 -action U -datafolder "c:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\HostController\Data"
Then again installed Search component with below command :
.\installconfig.ps1 -action I -datafolder "c:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\HostController\Data"
7. Force Active Directory Replication from a domain controller in the same AD Site as the Exchange 2013 server with repadmin /syncall /APeD.
8. Check on the Exchange Server with Get-MailboxDatabaseCopyStatus and review the ContentIndexState.
When the Content Index process has finished crawling we can see the index size of the folder is now 8GB and searching is now working as normal.

This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
