+description: "RAGFlow full-text-retrieval index of 14 KBs on http://10.10.10.254:9980/; landing 200, /api/v1/datasets 401. Complements NocoDB metadata with PDF full-text retrieval. Vector retrieval offline since 2026-07-17 (Robin desktop embedding + bge-reranker outage); metadata + document download still OK, KB content sync runs degraded via chunks-pull + local keyword grep."
