Document is changed by pdfsandwich but not searchable

[jacotec]

Hi,

I just need to get OCR to run before I can put Alfresco to production on a private/non-profit use. However, even after a day of try and error I can't get out of one issue.

The documents are OCR'ed when I put them into the folder with the rule, I see the convert.bin and tesseract threads running in top, afterwards the document got a new version number by "OCRd". But I can't search it. When I download the new PDF and open it in Acrobat, I still can't search. If I let Acrobat run its OCR on it and reupload it as a new version, also Alfresco will find the content.

Does anyone have an idea what's going on here? And help is highly appreciated :-)

OK ... after reading the FAQ three times and understanding what is meant I got it running by using ocrmypdf and putting the ocr.command into a shell script ;-)

Sorry for that ... maybe it'll help someone

I'm running into the same issues. Can you tell me step by step on how to fix it? what ocr command yo put into the shell script and where?
