A new study published on arXiv investigates the effectiveness of Retrieval-Augmented Generation (RAG) architectures, particularly in the context of agricultural advisory services for Bangladesh. The research highlights that aggregate retrieval scores can obscure significant performance variations across different query types and language conditions. For Bengali agricultural queries, BM25 and Hybrid RRF showed strong performance, but dense retrieval methods struggled with colloquial farmer queries compared to formal safety queries. The study also found that embedding task configuration and passage length can drastically alter reported R@10 scores, emphasizing the need for detailed performance reporting by language and query type in low-resource RAG evaluations.
