The approach uses one summary line per file plus each file's own table of contents, allowing retrieval to route down two levels.", "body_md": "# Multi-Document RAG: A Folder of Unrelated PDFs Is One Long Document with a Nested Outline\n\nEnterprise Document Intelligence [Vol.1 #14B] - No shared fields means no index to build.
