Researchers proposed Onyx, a disk-oblivious approximate nearest neighbor (ANN) search system that achieves 1.7–9.9× lower cost and 2.3–12.3× lower latency than the state-of-the-art oblivious ANN searc…

A developer's guide to vector search fundamentals for RAG design covers ANN algorithms like HNSW, distance metrics, metadata filtering, and BM25. It explains trade-offs between accuracy, speed, and co…

According to the "Is Grep All You Need?" study (arXiv:2605.15184), researchers wired both a literal grep tool and a vector-search tool into the same agents to run 116 LongMemEval questions, finding th…
