Regarding "user_patterns_suffix" have a look at tesseract manual page [1].
I am not sure if there is possibility to force tesseract choose ocr
output from dictionary (I never tried it ;-) )
But you can increase dictionary strength with variables
language_model_penalty_non_freq_dict_word and
language_model_penalty_non_dict_word. See FAQ[2].

I'd like to configure tesseract with a small dictionary (~200 words) and
tell it to always choose the best match in the dictionary. Is that possible?
Also, when inspecting the source code I saw a variable in dict.h called
"user_patterns_suffix". Is there any documentation around this? I'd like to
see if I can use it to tell Tesseract that my images will always contain
one serial number that always has 19 characters with no spaces.
