Self-Evolving Search Index

A research paper titled "Self-Evolving Search Index" argues that retrieval quality for LLM agents depends heavily on how effectively index keys expose the knowledge contained in each document, since retrieval relies on an index that represents each document through those keys. The work frames information retrieval as increasingly important as LLM agents tackle complex tasks involving diverse information needs.
