Multiple Sources in RAG Pipelines: Why More is Better

Incorporating multiple data sources into a retrieval-augmented generation (RAG) pipeline significantly enhances its capability by creating a dynamic and self-improving knowledge base that evolves with real-world usage. Unlike relying on a single source of truth, utilizing a variety of sources such as official documentation, support interactions, community discussions, and internal knowledge bases enriches the system with diverse perspectives and fills informational gaps. This multi-source approach not only captures different levels of detail and user contexts but also ensures the system remains up-to-date with real-time updates, ultimately improving retrieval quality and providing nuanced, practical responses. Although it requires more setup and maintenance, the resulting system becomes a resilient and valuable tool that better aligns with user needs and interactions, transforming a static knowledge base into a living system that grows alongside the product and its community.
