A developer encountered an issue where an LLM's retrieval system provided incorrect information due to poor document chunking. The system, designed to answer questions based on a pricing policy, failed because it split a document into arbitrary-sized pieces, separating headings from their corresponding paragraphs. This led the model to present a refund policy for business accounts to a user on the basic plan, as both sections contained similar wording but lacked context. The author suggests improving retrieval by preserving document structure, including headings and section information, and using this metadata for filtering and context when querying the model. AI
