I suppose if it only had letter-positions it would have to infer the word breaks, which could work, but might not. Using the analogy between words and letters, if I search for any part of two adjacent words, acroread finds it, even though it was only given the words as units. I can search for these successfully buaċaill óg buaċaill óg buaċaill ó uaċaill ó So it is not limited to searching only single full words, which is great. -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
