Hybrid RAG System: Vector Search + BM25 for Better Retrieval | LangChain Tutorial | Humanitarians AI

Описание: 🧠 Build a production-ready Hybrid RAG system that combines semantic vector search with BM25 keyword matching for more accurate and context-aware retrieval.
In this tutorial, we show how to create a hybrid question-answering system using LangChain, ChromaDB, and Groq’s Llama 3.3 70B, optimized for precision and scalability.

✅ What You’ll Learn:

🔍 Combine vector similarity search with BM25 keyword retrieval for hybrid accuracy
💾 Set up ChromaDB using HuggingFace embeddings
⚙️ Implement a weighted ensemble retriever with adjustable parameters
🧩 Explore document chunking strategies for improved recall
🚀 Build a QA agent powered by Groq API for fast and reliable inference

🧠 Project Highlight: Hybrid Retrieval System
• Integrates semantic understanding with exact keyword matching
• Handles both conceptual and literal queries effectively
• Ideal for enterprise search, documentation Q&A, and technical support bots

This tutorial helps you build a retrieval pipeline that’s smarter, faster, and more adaptable — a perfect foundation for real-world AI systems.
