However, that was still theoretical, just talk. To truly make RAG work, it must...

1 Introduction I've always had an idea—to build a chatbot for my blog that can understand the content of my blog posts and intelligently answer visitors' questions. While this requirement might seem simple at first glance, its actual implementation involves a series of unfamiliar and complex concepts: such as...
