Building a production RAG across a Book series: Retrieval, Reranking, and Hard Lessons
A developer built a retrieval-augmented generation (RAG) system for the "A Song of Ice and Fire" book series, which includes both a full-text search and a RAG-powered chat interface. The RAG system employs a multi-stage retrieval pipeline, starting with dense and sparse retrieval methods, followed by fusion and reranking, before finally generating an answer using Llama 3.3 70B. The developer emphasizes the importance of full-text search for certain queries and highlights the effectiveness of instruction-tuned embeddings and a robust reranking process for improving RAG performance.
