OCR writes text to PDF file

I've noticed that the text extraction from OCR only keeps the text in OpenKM. Once the file is downloaded, the text is no longer searchable.
Is it possible to use something like

It seems an interesting feature. I will add to OpenKM wishlist

You have no idea how hard I am wishing.
Otherwise there is a program in linux called pdfocr which looks like it just took PDF's and OCR'd them then wrote the text to the PDF. Don't know what the status of the project is though:

Yes, I found that also
. I ended up getting sick of trying to use linux to OCR a file and used the Adobe OCR program. Still, it looks like it worked in the past, so perhaps it is possible to get it to work well in the future; I'll have to look into it. I'll let you know what I find...
