Weaviate Podcast #141: Drowning in Documents author on why retrieving more and reranking isn't always better

Episode 141 of the Weaviate Podcast features Mathew Jacob, now a Ph.D. student at the University of Washington, diving deep into "Drowning in Documents" — the influential work he led at Databricks.
The paper's counterintuitive finding: in reranked retrieval pipelines, retrieving more candidates does not always yield better results, contradicting the common intuition of "retrieve more, rerank, get better." Weaviate calls it a must-read for anyone working in search and information retrieval, and one of their key references while scaling reranked retrieval.
