I want to include a website and all the URLs within that website as a knowledge base. Two part question - does the knowledge base recursively find all the URLs under the home page URL? For example, for realestate.com when I add that into the KB does Botpress also learn from realestate.com/locations? Or do I have to add every single URL (there can be hundreds) manually? Second question - is there a character limit for the knowledge base when trained from a website URL? If so, what is the character limit? Entire Websites can contain millions of characters
