## GraphRAG Entry Point (Recommended for Agents)

Single entry point for agents to query the knowledge graph using Graph Retrieval-Augmented Generation:

**[GraphRAG Query](http://localhost:3000/api/graphrag?q=your+question)**

- GET: `http://localhost:3000/api/graphrag?q=your+question&hops=1`
- POST: `http://localhost:3000/api/graphrag` with body `{"q": "your question", "hops": 1}`

Parameters:
- `q` (required): natural language or keyword query
- `hops` (optional, default 1, max 4): graph traversal depth — increase for richer context
- `type` (optional): restrict results to one entity type (see vocabulary table below)

Performs fulltext search across the Neo4j knowledge graph and returns matching entities together with their N-hop graph neighbourhood (relationship chains + connected nodes). Each result includes a `summary` field (biography / description / title) ready for LLM consumption without further parsing.

Example response shape:
```json
{
  "query": "...",
  "hops": 1,
  "type": null,
  "search_terms": "...",
  "total": 5,
  "graph_context": [
    {
      "type": "Person",
      "score": 5.36,
      "summary": "Alessandro Berti is currently a postdoctoral researcher at the Department of Physics …",
      "entity": { "id": "person_alessandro_berti", "name": "Alessandro Berti", "biography": "…" },
      "context": [
        { "distance": 1, "path_rels": ["AUTHORED"], "neighborType": "Publication", "neighbor": { "title": "Logarithmic Quantum Forking" } },
        { "distance": 1, "path_rels": ["HOLDS_CERTIFICATION"], "neighborType": "Certification", "neighbor": { "name": "Qiskit Advocate Certification" } },
        { "distance": 2, "path_rels": ["AUTHORED", "BELONGS_TO_TOPIC"], "neighborType": "Topic", "neighbor": { "name": "Quantum State Preparation" } }
      ]
    }
  ]
}
```

## GraphRAG Vocabulary

The fulltext index searches: name, title, description, biography, research_interests, field, type.
Use these keywords to find specific entity types:
