In case it helps someone, Yes there is a way to change the behaviour of 'minimum number of characters' I struggled with the same problem you have as well for a while
In this file, https://github.com/tesseract-ocr/tesseract/blob/master/ccmain/osdetect.cpp change the value of this constant to something like 5. Recompile and you are done. const int kMinCharactersToTry = 50 I have asked the developers to make a command line setting of that internal constant. If/When they do it I dont know.
