Ignore PDF Text
When a pdf file is uploaded, the app will normally use the text that is embedded in the pdf file. The "Ignore PDF Text" setting will ignore the text that is embedded in a pdf file and use an alternative text extraction algorithm instead. This can be useful in situations where a scanner did not convert the image data 100% correctly into text (this option is often called "OCR" or "searchable pdf" in the scan options). The "Ignore PDF Text" allows to ignore the text that a scanner has embedded into a pdf file and use an alternative text extraction algorithm. Please note this will make the processing of documents slower and is only recommended if our support team instructs you to enable this setting.
