Abstract

Conventional search systems used in enterprise settings often find it difficult to overcome the semantic gap between intention and document content on one hand within their information seek, hence making the process of information seeking to be inefficient and productivity low. At the same time, the use of Large Language Models (LLMs) per se is impeded by their factual error concerns, or hallucinations, which makes them unreliable when it comes to tasks that require knowledge-intensive efforts within companies. The present paper presents Hy-Search, a new smart search model that uses a Hybrid Retrieval-Augmented Generation (RAG) model to help overcome these two challenges. This system is a combination of a dense semantic retriever and sparse lexical retriever, ingested with a tutorialized context into a generative LLM. Our full empirical assessment is based on a corpus of 15,000 technical documents of a giant company. Its results indicate that Hy-Search can perform at a state-of-the-art, extremely surpassing standard baselines of the search process based on keywords and pure dense retrieval. More importantly, the RAG architecture has a 73 per cent lower incidence of hallucinations per an isolated LLM, and user experiments have a 94 per cent task completion rate and 87 per cent preference over existing search systems. This publication confirms the fact that a hybrid RAG solution pro- is a scaleable, factuallyfounded, and user-friendly solution to next-generation 3rd generation enterprise knowledge discovery.
