    You'll learn how a mid-sentence chunk split causes a RAG pipeline to confidently deny a fact that's actually in the source docs, and how to find and fix that failure in your own pipeline.

    Why bad chunking breaks RAG before embeddings can help
    day 17 · Data & Retrieval Engineering in 30 Days

    Three weeks of swapping embedding models and tuning rerankers won't fix a retriever that's been fed half a function signature — here's the 10-minute check that tells you if chunking, not your model, is the real problem.

    How bad chunking breaks retrieval before embeddings run
    day 10 · LLM Engineering in 30 Days

    The answer your user needed didn't get lost in search — it got cut in half before your embedding model ever laid eyes on it, and there's a 20-minute check that proves it.

    If your retrieval eval scores refuse to budge no matter which embedding model you throw at them, the fix isn't a bigger model — it's the chunk boundary that quietly amputated your answer before encoding ever happened.
