Advanced RAG

📌 Planned placeholder page: this page is reserved for "Advanced RAG — Advanced retrieval techniques, index structures, reranking, GraphRAG and evaluation", and the content will be filled in progressively along with learning.

Planned Content

• [ ] Index structures: structural chunks, sentence windows, parent-child auto-merging, summary indexes
• [ ] Retrieval strategies: hybrid search with RRF, query transformations, adaptive retrieval, Agentic RAG, GraphRAG
• [ ] Reranking and context engineering: reranker tiers, compression, position effects, citation grounding
• [ ] Retrieval evaluation: metrics, gold sets, ablation order
• [ ] Production: incremental updates, ACL filtering, caching, cost structure

Next Steps

• [ ] Complete this page item by item against the planning checklist in the Domain Overview
• [ ] Add runnable examples and pitfall records for each entry
• [ ] Change the status from "Planned" to "Collected" when done
