Three Kinds of RAG Corpus, and What It Costs to Build for the Wrong One
Enterprise document collections are not one kind of thing, and treating them all as a flat pile of chunks for similarity search is the reason RAG systems that work on a demo folder fail on a real shelf. Three diagnostic questions determine which of three shapes a collection has: an unrelated pile, a homogeneous typed corpus, or bundles of case files, each requiring a different architecture. A re-ranker does not fix a missing-candidate problem, and version/supersession relationships cut across all three shapes and need their own relations table and validity dates. A baseline test on five NIST PDFs shows four out of five document-level calls returning nothing usable, illustrating the wasted work of querying every document instead of narrowing the candidate set first.
