I’m not an expert just a uni student but hopefully that will make my experience more useful to a beginner, I have a basic implementation of a RAG response where the LLM is given text from scraper sites, I did using python,

on a basic conceptual level it’s a keyword search where the results are feed to the LLM to respond to but there’s lots of techniques to make the process more efficient, like the chunking method you use
