2. I can't effectively OCR them for many non-English language (at least - unless it's made some advances in OCR for some languages for which it's lacking). Also, if I do OCR anything, I then need to correct the mistakes, which takes a h-u-g-e amount of time even when the OCR works relatively well.
- The scanned documents are stored in the filesystem in PDF format, so you can certainly access them without going through the web application.
- OCR doesn't have to be perfect, because it's just being used to locate a specific document when you need it. So if you have 1788 documents and you want to find your apartment lease, you search for "lease" and there's a very good chance that word will be found in the correct document. That's the whole point - storing documents with a low amount of manual effort, in a way that makes it very easy to find them when you need them.
