Select OCR languages from a code page
This policy setting allows selecting of OCR (Optical Character Recognition) languages that belong to one of the supported code pages. If you enable this policy setting the selected OCR languages are used in OCR processing during the indexing of TIFF files. The default system language is ignored unless it is among the selected OCR languages. If you disable or do not configure this policy setting only the default system language is used. All selected OCR languages must belong to the same code page. If you select languages from more than one code page the entire OCR language selection is ignored and only the default system language is used. Re-indexing is not initiated when you enable this policy and selecting OCR languages. This policy setting only applies to the indexing of new files unless re-indexing is initiated manually.
Force TIFF IFilter to perform OCR for every page in a TIFF document
This Group Policy setting lets users turn off the performance optimization so that the TIFF IFilter will perform OCR for every page in a TIFF document which allows indexing of all recognized text. By default the TIFF IFilter optimizes its performance by skipping OCR (Optical Character Recognition) for document pages that have non-textual content (for example pictures). In some cases pages that contain text can be misclassified as non-text pages. If this is the case the text in these pages will not be indexed. If you enable this setting TIFF IFilter will perform OCR for every page in a TIFF document to index all recognized text. Therefore the OCR process will be slower. This decrease in performance can be significant if there are lots of non-textual pages (pictures) in TIFF documents on the system. If you disable or do not configure this setting TIFF IFilter will optimize its performance by skipping non-textual content during the OCR process.
