How to make use of the already existing OCR data of a document rather than running another OCR step using Digitize Document Activity?
The "Force Apply OCR" option - Force apply OCR only tells the Digitize Document Activity to use the OCR engine set there, instead of trying to get the digital version of the PDF.
The DOM and Document Text that are required by UiPath Document Understanding activities need to match and this is enforced by each activity. If only the text is present, then it is difficult to produce a DOM to match it later.
If the document contains the background image of the scanned document, it will always be OCR'd because there is usually a lot of content in the images themselves.
