Try a sample question
A RAG system struggles with vague queries like 'What are the main issues discussed in these reports?'. The retriever returns broad, low-relevance chunks. Which advanced retrieval technique generates multiple specific sub-queries to improve retrieval coverage?
A.HyDE: generate a hypothetical answer document and use its embedding for retrieval
B.Multi-query retrieval: use an LLM to decompose the original query into several specific sub-queries, run each independently, then union and deduplicate retrieved chunks
C.Step-back prompting: abstract the query to a higher conceptual level before retrieval
D.Parent-child chunking: retrieve small child chunks but return their parent sections to the LLM

Frequently asked questions
- What does the Advanced Retrieval Patterns check test?
- The check covers hyde (hypothetical document embeddings), query decomposition, multi-hop retrieval, query expansion, step-back prompting — when simple top-k retrieval fails and these patterns rescue it.. Questions span beginner to advanced difficulty and test both conceptual understanding and practical trade-off reasoning.
- What keywords should I know for Advanced Retrieval Patterns?
- Key concepts include: HyDE, hypothetical document embeddings, query decomposition, multi-hop, query expansion, step-back prompting, RAG fusion. These frequently appear in rag & retrieval systems interviews at product and infrastructure companies.
- How many questions are in the check?
- Each check has 10 questions — a mix of MCQ and short-answer. You get scored by dimension (e.g., scalability, consistency) so you know exactly where to focus.
- How long does it take to study Advanced Retrieval Patterns?
- Most engineers spend around 3 hours on this module. The check itself takes about 10–15 minutes. You can retake it up to 3 times per day.
- What prerequisite knowledge do I need before Advanced Retrieval Patterns?
- Advanced Retrieval Patterns builds on RAG Prompt Design. Complete those first for the best results.
- Is HyDE, hypothetical document embeddings, query decomposition covered?
- Yes. The Advanced Retrieval Patterns module covers HyDE, hypothetical document embeddings, query decomposition among other key concepts. The check includes questions that reflect real rag & retrieval systems interview patterns.
