Yes this is a known issue that was just fixed, and it will be in the next 2.14 patch release:
Is there a way to view what text was OCRed from an attachment? I have moved up to the latest 2.14.19 on Windows and several screenshots that I have put in a note are not being found by the text in them. Looking at the Console, I can copy/delete/paste the image back in and see that the OCR process finds it and says it processes with no errors.
I have downloaded tesseract and run the same image through it. It finds the text, including the text I was using for the search.
Is there a way to view what text was OCRed from an attachment?
Also would like to know that
Is there a possibility to search OCR only in one note? I tried filtering the notes with id:... but it didn't work. The easiest way would be if i could just do the normal ctrl-F search and it would search also through the images.
