Hello everyone, I am developing a chatbot designed to answer questions using a knowledge base (KB) trained through web scraping. The bot performs well with queries directly related to the scraped content. However, it struggles with related questions outside the scope of the initial KB, as shown in the attached example. Look when I enter "How Can I use the Citrus Mojo" doesn't have a response I seek to augment my chatbot's functionality to resemble ChatGPT, where it can search for information when encountering unknown queries. Could you advise on integrating such a feature?
