Fixed-size chunking and vector-only search fail on contracts, statements and clinical records. See how hybrid search, reranking and structure-aware chunking fix it.
How to build RAG that respects permissions, keeps PII out of your vector store and can run air-gapped — with patterns for finance, healthcare, legal and government.
Most disappointing RAG demos are blamed on the LLM. In practice the model is rarely the problem — the passages it was given are. Here is where retrieval breaks down and how to fix it.
Keyword search is precise but literal; semantic search understands intent but can be vague. Combining them, then reranking, is how production systems get both.
Regulated documents have rules of their own: clauses that must stay together, tables that must add up, and sensitive fields that must never leak. Here is how RAG adapts.
Specs, runbooks, contracts and exported tickets pile up every week. A document search layer that stays in sync with your sources keeps knowledge usable instead of buried.
Once sensitive values are embedded in a vector store they are hard to remove. Tokenising them before indexing keeps raw data out of the index entirely.
Hosted retrieval gets you moving fast; keeping vectors in your own database gives you control. Here is how to decide — and why the choice should not lock you in.
