256986 Description of the Microsoft Windows Registry

SYMPTOMS

Microsoft Index Server cannot query documents over 256 kilobytes (KB) in size that have unknown file name extensions.

CAUSE

The default limit for files with unknown file name extensions is 256 KB. This limit is set to prevent indexing of very large files.

RESOLUTION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To work around this problem, follow these steps:
  1. Start the Registry Editor (Regedt32.exe).
  2. In the following registry key, set MaxFileSizeFiltered to a value larger than 256 KB in units of 1024 bytes:
         hklm\system\currentcontrolset\control\contentindex\MaxFileSizeFiltered
  3. Close Registry Editor.
  4. Restart the Content Index Service.
  5. Rebuild the catalog.

STATUS

This behavior is by design.
