RAGless is a novel semantic retrieval system designed for closed-domain FAQ knowledge bases. It operates by generating multiple question variants for each answer during ingestion, which are then embedded. When a user queries the system, their question is embedded, and the top-K nearest question variants are retrieved. The system aggregates scores for these variants by answer ID, with the answer receiving the highest aggregated score being returned. This approach eliminates the generation step found in standard RAG systems, focusing on question-level retrieval for improved precision in predefined answer spaces. AI
