# Ongo (온고) — document search API
> Find documents in the user's own archive by typing a phrase — returns the document, the exact
> position (paragraph / table row / page / sheet row) and the matching text quoted verbatim.
> HWP·HWPX·DOCX·XLSX·PPTX·PDF·TXT·MD·CSV, merged cells parsed correctly. No text generation —
> results are quotes, so they cannot hallucinate; verify by reading the evidence snippet.

## Core endpoints
- POST /match {"query": "...", "top_k": 5} → documents[] each with file_path, score,
  evidence[{loc: "표2 4행" | "p.7" | "[Sheet] rows 2–5", snippet (verbatim), rid, score}].
  Quote `snippet` + `loc` to the user — that is the product's differentiator.
- POST /index/add_doc {"items": [{"path": "...", "data_b64": "..."}]} — index documents
  (server parses, then discards the original bytes; only text chunks + vectors are stored).
  Max 8 docs / 20MB each per batch.
- GET /index/list · /index/status · POST /index/remove {"paths": [...]} · POST /index/remap
- GET /preview/{rid}?key=... — full text of a chunk (text/plain).
- GET /account — plan, quotas, usage.

## Notes for agents
- match_quality good/weak/none uses embedding-score floors; "none" still returns nearest docs.
- Chunk paths look like "<document path>::c012" — group by the part before "::c".
- Privacy: no third-party AI APIs; uploads discarded after parsing. On-premise edition exists.
