When you activate optical character recognition (OCR) for Tagged Image File Format (TIFF) files, TIFF files may be incorrectly indexed in Microsoft SharePoint Portal Server 2001. As a result, you may receive inconsistent search results when you query the workspace index for TIFF files.
For example, TIFF files that are returned in the search results of a previous search are not returned when you perform the same search after the index is updated.
This problem may occur if the OCR engine incorrectly processes TIFF documents.
This problem was first fixed in a hotfix that is now contained in a service pack. If you have installed SharePoint Portal Server 2001 Service Pack 3 or a later service pack, you do not have to apply the hotfix.

When you activate OCR, SharePoint Portal Server scans the TIFF document, and then tries to recognize characters so that additional information can be included in the index. By default, OCR is not activated. For more information about OCR and how to activate it, see Help in SharePoint Portal Server Administrator.
