Google's New MUVERA Algorithm Improves Search

Google announced a new multi-vector retrieval algorithm called MUVERA that speeds up retrieval and ranking, and improves accuracy. The algorithm can be used for search, recommender systems (like YouTube), and for natural language processing (NLP).

Although the announcement did not explicitly say that it is being used in search, the research paper makes it clear that MUVERA enables efficient multi-vector retrieval that appears suitable for large-scale applications by reducing the problem to single-vector MIPS, allowing the use of off-the-shelf retrieval systems (existing infrastructure) and achieving lower latency and memory usage.
