In the C-API book, similar docs of the KP "dict" and "dictionary" are different. Not just that, the sim_score of dict is 1.0 whereas for the dictionary is 0.825. We should make appropriate changes to ensure that the sim_docs of KP and their abbreviations are the same. I think this logic is already implemented, we need to check why is it not getting applied in this case. Eventually, we would want to increase the sim_score of "dictionary" KP as well.
