How to Move the Gather Logs for Full-Text Indexing

  • Article

 

You can improve performance of servers that perform full-text indexing by moving the gather log files from the system drive to a higher performance drive. Move the gather logs by performing the following procedure.

Before You Begin

This procedure is one of six steps that you should perform when optimizing full-text indexing. For more details about this entire process, see How to Optimize Full-Text Indexing.

Warning

Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.

Be sure that you specify a valid directory because full-text indexing does not function if you specify an invalid directory. The Microsoft Search service does not need to be running when you edit the registry key. However, if you edit the registry key while the Microsoft Search service is running, you must restart the service after you make the change for the change to take effect.

Procedure

To move the gather logs

  1. Start Registry Editor.

  2. In the Registry Editor, specify the preferred location for gather logs using the following registry key:

    HKEY_LOCAL_MACHINE\Software\Microsoft\Search\1.0\gather\ExchangeServer_<instance>\<index name>\StreamLogsDirectory

Note

On a cluster, before you change the StreamLogsDirectory registry key, make sure that the MSSearch resource is online. Also, make sure that you are editing the correct node by using Cluster Administrator to verify the node on which the group is running. After you change the registry key, use Cluster Administrator to restart the MSSearch resource by taking it offline, and then bringing it back online.
