I have a set of over 1000 words which forms the vocabulary of my bot. How do I implement this in botlibre? I see the way the colors set is done in json using name value pairs but here, it is just a set of words. If the input from the user does not contain those words, then the question may not pertain to information security and the bot should not try to search or answer the question. I still however need the question to be logged. Can I do this on the bot libre platform?
