# Semantic search over a space's indexed files

GET https://api.cloudraker.com/spaces/{spaceId}/search

Runs semantic search over every indexed file in the space `:spaceId`. Authorization: the caller needs `space:read` on the space; organization administrators bypass this check. Lacking access returns **404** (existence is hidden), never 403. Query params: `q` (required) is the natural-language query text; callers never send vectors. An empty or whitespace-only `q` returns 400. `limit` (optional, default 20) is a positive integer, capped at 100; larger values are clamped to 100, and a non-integer or `< 1` returns 400. The search is always scoped to the space in the path. Returns `{ matches }`, an array ranked by relevance; each match has `id`, `namespace`, `tags[]`, `score` (higher = closer), and a `metadata` object carrying file grounding (file id, page, bbox, and/or audio timecode) when the source was indexed with it. There is no cursor pagination — bound the result count with `limit`.

Reference: https://docs.cloudraker.com/workspace/api/search/space

## Authentication

- `Authorization` header (bearer token, required)

## Request

### Path parameters

- `spaceId` (string, required)

### Query parameters

- `q` (string, required) — Natural-language query text. Empty or whitespace-only returns 400. Callers never send vectors.
- `limit` (integer, optional, default: 20) — Maximum matches, clamped to 100. A non-integer or value below 1 returns 400.

## Response

### 200

Ranked semantic matches within the space.

- `matches` (list of object, required) — Ranked by relevance. No cursor.
  - `id` (string, required) — Chunk id of the match.
  - `namespace` (string, required)
  - `tags` (list of string, required)
  - `score` (double, required) — Relevance; higher is closer.
  - `metadata` (map from string to any, optional) — File grounding when the source was indexed with it: file id, page, bbox, and/or audio timecode.

## Examples

**Response**

```json
{
  "matches": [
    {
      "id": "string",
      "namespace": "space/3f1c…/file_01J…",
      "tags": [
        "string"
      ],
      "score": 1.1,
      "metadata": {}
    }
  ]
