#### JSON Search API

**Endpoints**:
- `GET /api/v1/documents?q={query}` (recommended)
- `GET /json/?q={query}` (legacy, for backward compatibility)

**Parameters**:
- `q` - Query string
- `num` - Results per page (default: 20)
- `start` - Starting offset (default: 0)
- `fields.label` - Label filter
- `lang` - Language preference

**Example**:
```bash
# Using the recommended endpoint
