A new study published on arXiv investigates the performance of information retrieval systems when faced with complex, set-compositional queries. Researchers found that while neural retrieval methods significantly outperform traditional BM25 on some benchmarks, their effectiveness diminishes on more controlled datasets designed to test constraint satisfaction. The study highlights a consistent degradation in performance across all methods as query complexity increases, with lexical retrieval showing more stable results than dense approaches. AI
