You cannot rescan the Indexing Service scope that has a full path of over 13 characters on a computer that is running Windows Vista or Windows Server 2008
Consider the following scenario:
- You install Indexing Service on a computer that is running Windows Vista or Windows Server 2008.
Note: For more information about Indexing Service and about the Indexing Service scope, see the “More Information” section.
- You rescan the Indexing Service scope by using the Indexing Service Microsoft Management Console (MMC) snap-in window or by using a script to access the Indexing Service Administrative objects.
Note: A scan is when an Indexing Service scope (a directory or set of directories that are to be included in the index) is examined. The scan examines the scope to check whether any files were added, deleted, or updated since the last time that the directory was indexed.
In this scenario, the rescan may fail without returning an error. Therefore, when the index is searched, new documents cannot be located in the index.
Note: This problem typically occurs when the Indexing Service scope has a full path length of more than 13 characters.
