I get HAX 6 5-5,- with Tesseract 3.0 What I find remarkable is that half the folks on this forum would love to disable the word recognition (i.e. dictionary), the other half would like to enable it - and absolutely no one knows how to enable/ disable the dictionary nor can say for sure if it's actually enabled or not by default. I am included in the group of the clueless - we have scanned thousands of business cards and still have no idea whatsoever what the hell is going on with that elusive dictionary.
I gather from Jimmy's recent answer that the dictionary is contained in a single file of type text, one word per line, in a file called eng.user-words (any support for regular expressions there? for example to say that [\\d]*th is a common word) placed in the Tessdata folder but we await final confirmation. Is it enough that the file exists? Does removing the file disable the dictionary? Clearly many have used the dictionary but sadly it appears that these knowledgeable people deserted this forum once they got the answers they need - if you see one of these gentlemen (or ladies, yes) roaming the streets, please admonish them for not staying subscribed to forum messages to give back in helping others!
