Top 3 RAG Retrieval Strategies: Sparse, Dense, & Hybrid Explained

Top 3 RAG Retrieval Strategies: Sparse, Dense, & Hybrid Explained

🚀 New short course with Qdrant: Multi-vector Image Retrieval. Taught by Kacper Łukawski, Senior Developer Advocate at Qdrant, the course shows how multi-vector techniques outperform single-vector methods by matching text tokens to image patches directly. You’ll implement ColBERT to understand multi-vector search, apply ColPali for patch-level image retrieval, reduce memory with quantization and pooling, and use MUVERA to enable fast HNSW search. The course concludes with a full multi-modal RAG

BM25: "why won't you die?!"> the lexical retriever BM25 with appropriate setup outperforms neural rankers in most cases; notably, gpt-oss-20b with BM25 on the passage corpus achieves the highest answer accuracy across all retrieval settings in our study; BERT-based learned sparse and multi-vector dense retrievers generalise better than LLM-based single-vector dense retrievers; and re-ranking remains highly effective
