With the increasing adoption of Large Language Models A production-ready, generalizable framework for LLMbased (LLMs) in enterprise settings, ensuring accurate and reliable QA systems built on Elasticsearch question-answering systems remains a critical challenge. A flexible hybrid retrieval mechanism combining dense Building upon our previous work on domain-specific and sparse search methods question answering about Adobe products (Sharma et al. A comprehensive evaluation framework for assessing 2024), which established a retrieval-aware framework with QA system performance self-supervised training, we now present a production-ready, Empirical analysis demonstrating the effectiveness of our generalizable architecture alongside a comprehensive evaluation approach across various metrics methodology. Our core contribution is a flexible, scalable framework built on Elasticsearch that can be adapted Through this work, we provide not only theoretical insights for any LLM-based question-answering system. This framework but also a practical, deployable solution for building reliable seamlessly integrates hybrid retrieval mechanisms, domain-specific question-answering systems that can combining dense and sparse search with boost matching, be adapted to various enterprise needs.
