Prompt engineering is the art of crafting precise inputs to get the best results from large language models. Learn core principles like few-shot prompting, chain-of-thought, and RAG-and how small changes in wording can dramatically improve AI output.
Hybrid search combines semantic and keyword retrieval to fix RAG's biggest flaw: missing exact terms. Learn how it boosts accuracy for code, medical terms, and legal docs-and when to use it.
