Exam Certified Generative AI Engineer Associate topic 1 question 59 discussion

A. Add the section header as a prefix to chunks By tagging each chunk with its section heading (e.g. “Vacation Policy,” “Leave of Absence,” etc.), you give the retriever additional semantic signals so it can better match queries to the right policy area. This often dramatically boosts retrieval relevance for structured docs. D. Increase the document chunk size If your chunks are too small, key details may be split across multiple chunks and never surface together in the top-k. Enlarging the chunk window (while still staying under your model’s context limit) lets each chunk carry more contiguous context, so the retriever can return more complete sections. Options B and E address text splitting or generation tuning but won’t solve retrieval gaps; option C (bigger embedding model) was already tried indirectly when swapping embedding LLMs and didn’t fix the core issue of missing context.
