        description = "Semantic search engine for open data portals.

Ceres indexes datasets from open data portals (CKAN, Socrata, DCAT) and provides
semantic search capabilities using vector embeddings.

## Features

- **Semantic Search**: Find datasets using natural language queries
- **Portal Management**: Configure and monitor data sources
- **Harvest Operations**: Trigger and track data synchronization
- **Export**: Download datasets in JSON, JSONL, or CSV format

## Quick Start

1. Check server health: `GET /api/v1/health`
2. Search for datasets: `GET /api/v1/search?q=air+quality`
3. View statistics: `GET /api/v1/stats`
