[paripolt]

I use OpenKM Professional version 6.4.22 for windows .I can't find any OCR feature.
I try to input parameter system.ocr = C:\Program Files (x86)\Tesseract-OCR\tesseract ${fileIn} ${fileOut} -l esp.
What I have to do next?

The file name should be tesseract.exe
Did you installed spanish dictionary ?
After these changes, take an image ( into tesseract folders I think there's some sample, or simply check an image from tesseract side and then try into OpenKM ). Take in mind documents going into pending queue ( Administration > stats > pending queue ) you should be waiting until de document be indexed before trying to do some query.
