I have created a public bot called cisobot. It answers questions on information security. I want it to search duckduck go if it does not know an answer. I have created the first version of this bot in a language called quorom which is similar to java. However, I am trying to move the bot to botlibre. Right now, if the bot does not something it says "unknown" when my program sees this response, it searches duckduckgo for a response. If that fails, the bot asks the user to talk about information security. How do I implement the search functionality in botlibre?
