98% sounds good but that remaining 2% is crucial. I do OCR on a lot of my scanned documents to make them searchable and easy to copy text. I've tried a number of OCR programs but even after a lot of training something like Omnipage will still think a lower case l is a 1 in the middle of a word. It seems like it should be easy to put in a rule that says it is unlikely that a document will have a number surrounded by letters (without spaces) but that doesn't seem possible.

If you need that receipt from the one time you bought a garden hose, searching for “garden” and “hose” will probably get you there, even if the OCR tool read “garden h0se” or “g4rden hose”.
