Neo4j GraphRAG Skill

When to Use

  • Building GraphRAG retrieval pipelines with neo4j-graphrag Python package
  • Choosing between VectorRetriever, HybridRetriever, VectorCypherRetriever, HybridCypherRetriever
  • Writing retrieval_query Cypher fragments for graph-augmented context
  • Wiring retriever + LLM into a GraphRAG pipeline
  • Using LLM-routed multi-retriever with ToolsRetriever
  • Debugging low retrieval quality
  • Integrating Neo4j with LangChain, LlamaIndex, or Haystack

When NOT to Use

  • KG construction from documents → neo4j-document-import-skill
  • Plain vector/semantic search without graph traversal → neo4j-vector-index-skill
  • Hybrid search that combines vector with fulltext or other ranked sources → neo4j-vector-index-skill
  • GDS algorithms (PageRank, Louvain, node embeddings) → neo4j-gds-skill
  • Agent long-term memory → neo4j-agent-memory-skill
  • Writing raw Cypher queries → neo4j-cypher-skill

Retriever Selection

Has fulltext index?
  YES → Hybrid variants (HybridRetriever / HybridCypherRetriever)
  NO  → Vector variants (VectorRetriever / VectorCypherRetriever)

Need graph traversal after vector lookup?
  YES → Cypher variants (VectorCypherRetriever / HybridCypherRetriever)
  NO  → plain variants

Natural-language-to-Cypher?        → Text2CypherRetriever (no embedder needed)
LLM should route between retrievers? → ToolsRetriever
Vectors stored in external DB?      → WeaviateNeo4jRetriever / PineconeNeo4jRetriever / QdrantNeo4jRetriever

Step 2 — Choose Retriever

Has fulltext index? YES → Hybrid variants (better recall)
                   NO  → Vector variants (baseline)

Needs graph context after vector lookup? YES → Cypher variants
                                         NO  → plain variants

For natural-language-to-Cypher? → Text2CypherRetriever (no embedder needed)
For multi-tool LLM routing?     → ToolsRetriever
Using external vector DB?       → WeaviateNeo4jRetriever / PineconeNeo4jRetriever / QdrantNeo4jRetriever
RetrieverVectorFulltextGraphWhen to use
VectorRetriever✓——Baseline; quick start
HybridRetriever✓✓—Better recall; no graph context
VectorCypherRetriever✓—✓GraphRAG without fulltext
HybridCypherRetriever✓✓✓Production GraphRAG — default choice
Text2CypherRetriever——✓LLM generates Cypher; no embedder
ToolsRetrievervariesvariesvariesMulti-retriever LLM routing

For custom Cypher hybrid search outside the neo4j-graphrag retriever APIs, use neo4j-vector-index-skill.

Vector backend selection [v1.16+, auto]: on Neo4j 2026.01+ all four vector/hybrid retrievers auto-route through the Cypher 25 SEARCH ... WHERE clause when filters are SEARCH-compatible (simple AND comparisons) and all filter props are declared in the index WITH [n.prop] list. $or, $in, $like, or undeclared props → automatic fallback to db.index.vector.queryNodes() procedure path (with warning log). Declare filterable properties via filterable_properties=[...] on create_vector_index().

Step 3 — Create Indexes (run once)

// Vector index (all retrievers need this)
CREATE VECTOR INDEX chunk_embedding IF NOT EXISTS
FOR (c:Chunk) ON (c.embedding)
OPTIONS { indexConfig: {
  `vector.dimensions`: 1536,
  `vector.similarity_function`: 'cosine'
} };

// Fulltext index (Hybrid retrievers only)
CREATE FULLTEXT INDEX chunk_fulltext IF NOT EXISTS
FOR (c:Chunk) ON EACH [c.text];

// Confirm ONLINE before ingesting:
SHOW INDEXES YIELD name, state
WHERE name IN ['chunk_embedding', 'chunk_fulltext']
RETURN name, state;
// Both must show state = 'ONLINE'

If index not ONLINE: wait, poll every 5s. Do NOT start ingestion until ONLINE.

Step 4 — Core Pattern (HybridCypherRetriever)

from neo4j import GraphDatabase
from neo4j_graphrag.embeddings import OpenAIEmbeddings
from neo4j_graphrag.generation import GraphRAG
from neo4j_graphrag.llm import OpenAILLM
from neo4j_graphrag.retrievers import HybridCypherRetriever

# retrieval_query: Cypher fragment executed after the vector/fulltext lookup.
# Auto-injected variables:  node  (matched node)   score  (similarity float)
# MUST include a RETURN clause.  score must appear in RETURN.
retrieval_query = """
MATCH (node)<-[:HAS_CHUNK]-(article:Article)
OPTIONAL MATCH (article)-[:MENTIONS]->(org:Organization)
RETURN node.text AS chunk_text,
       article.title AS article_title,
       collect(DISTINCT org.name) AS mentioned_organizations,
       score
"""

retriever = HybridCypherRetriever(
    driver=driver,
    vector_index_name="chunk_embedding",
    fulltext_index_name="chunk_fulltext",
    retrieval_query=retrieval_query,
    embedder=embedder,
)

llm = OpenAILLM(model_name="gpt-4.1", model_params={"temperature": 0})

rag = GraphRAG(
    retriever=retriever,
    llm=llm,
)

response = rag.search(
    query_text="Who does Alice work for?",
    retriever_config={"top_k": 5},
)
print(response.answer)
driver.close()

VectorCypherRetriever

from neo4j_graphrag.retrievers import VectorCypherRetriever

retriever = VectorCypherRetriever(
    driver=driver,
    index_name="chunk_embedding",
    retrieval_query=retrieval_query,
    embedder=embedder,
)

response = rag.search(
    query_text="What happened at Apple?",
    retriever_config={"top_k": 10},
)

Text2CypherRetriever

Translates natural language to Cypher using an LLM. No embedder required.

Security (v1.16.0+): Every LLM-generated Cypher is run through EXPLAIN first. Any statement classified as write/destructive raises Text2CypherRetrievalError instead of executing — prevents prompt-injection attacks.

from neo4j_graphrag.retrievers import Text2CypherRetriever

retriever = Text2CypherRetriever(
    driver=driver,
    llm=OpenAILLM(model_name="gpt-4.1"),
    neo4j_schema=None,       # None = auto-fetch schema from DB; pass string to trim
    examples=[
        "Q: Who works at Neo4j? A: MATCH (p:Person)-[:WORKS_AT]->(c:Company {name:'Neo4j'}) RETURN p.name"
    ],
)
results = retriever.search(query_text="Which people work at Neo4j?")

ToolsRetriever (LLM-routed multi-retriever)

from neo4j_graphrag.retrievers import ToolsRetriever

tools_retriever = ToolsRetriever(
    llm=llm,
    retrievers=[vector_retriever, text2cypher_retriever],
)
# LLM decides which retriever(s) to invoke per query

# Convert any retriever to a standalone Tool:
tool = vector_retriever.convert_to_tool()

results = retriever.search(
    query_text="quarterly earnings",
    top_k=5,
    filters={
        "date": {"$gte": "2024-01-01"},
        "source": {"$eq": "10-K"},
    },
)
# Operators: $eq  $ne  $lt  $lte  $gt  $gte  $between  $in  $like  $ilike

query_params (parameterized retrieval_query)

retrieval_query = """
MATCH (node)<-[:HAS_CHUNK]-(a:Article)-[:MENTIONS]->(org:Organization {name: $entity_name})
RETURN node.text, a.title, score
"""

# Pass via retriever.search directly:
results = retriever.search(
    query_text="What happened at Apple?",
    top_k=10,
    query_params={"entity_name": "Apple"},
)

# Or via GraphRAG.search:
response = rag.search(
    query_text="What happened at Apple?",
    retriever_config={"top_k": 10, "query_params": {"entity_name": "Apple"}},
)

Cypher 25 SEARCH Clause (v1.16.0, Neo4j 2026.x+)

# Enable SEARCH clause syntax in vector/hybrid retrievers (requires Neo4j 2026+)
retriever = VectorRetriever(
    driver=driver,
    index_name="chunk_embedding",
    embedder=embedder,
    use_search_clause=True,
)

ORDER BY on Cypher Retrievers (v1.16.0)

results = retriever.search(
    query_text="...",
    top_k=10,
    order_by="score DESC",
)

If neo4j_schema=None: retriever fetches schema automatically. For large schemas, pass a trimmed string to reduce LLM prompt size.

Destructive-query guard [v1.16+]: Text2CypherRetriever runs EXPLAIN on the generated Cypher before execution and rejects queries that produce writes (CREATE, MERGE, DELETE, SET, REMOVE, etc.). LLM-generated writes are never executed against the graph.

Custom Prompt Template

from neo4j_graphrag.generation.prompts import RagTemplate

template = RagTemplate(
    template="""Answer using ONLY the context below.
Context: {context}
Question: {query_text}
Answer:""",
    expected_inputs=["context", "query_text"],
)

rag = GraphRAG(retriever=retriever, llm=llm, prompt_template=template)

return_context and response_fallback

response = rag.search(
    query_text="...",
    retriever_config={"top_k": 5},
    return_context=True,                        # include raw retrieved chunks
    response_fallback="No relevant context.",   # skip LLM call if retriever returns nothing
)
print(response.answer)
print(response.retriever_result)    # RawSearchResult when return_context=True

Message History (multi-turn)

from neo4j_graphrag.message_history import InMemoryMessageHistory

history = InMemoryMessageHistory()
r1 = rag.search(query_text="Who is Alice?", message_history=history)
r2 = rag.search(query_text="Where does she work?", messa

response = rag.search(
    query_text="Who does Alice work for?",
    retriever_config={"top_k": 5},

## VectorCypherRetriever

```python

## Text2CypherRetriever

Translates natural language to Cypher using an LLM. **No embedder required.**

    ],
)
results = retriever.search(query_text="Which people work at Neo4j?")
```

---

## ToolsRetriever (LLM-routed multi-retriever)

```python
from neo4j_graphrag.retrievers import ToolsRetriever

tools_retriever = ToolsRetriever(
    llm=llm,
    retrievers=[vector_retriever, text2cypher_retriever],
)
# LLM decides which retriever(s) to invoke per query

# Convert any retriever to a standalone Tool:
tool = vector_retriever.convert_to_tool()
```

---

## Filters (pre-filter before vector search)

```python
results = retriever.search(
    query_text="quarterly earnings",
    top_k=5,
    filters={
        "date": {"$gte": "2024-01-01"},

```

---

## query_params (parameterized retrieval_query)

```python
retrieval_query = """
MATCH (node)<-[:HAS_CHUNK]-(a:Article)-[:MENTIONS]->(org:Organization {name: $entity_name})
RETURN node.text, a.title, score
"""

# Pass via retriever.search directly:
results = retriever.search(
    query_text="What happened at Apple?",
    top_k=10,
    query_params={"entity_name": "Apple"},
)

# Or via GraphRAG.search:
response = rag.search(
    query_text="What happened at Apple?",
    retriever_config={"top_k": 10, "query_params": {"entity_name": "Apple"}},
)
```

---

## Cypher 25 SEARCH Clause (v1.16.0, Neo4j 2026.x+)

```python
# Enable SEARCH clause syntax in vector/hybrid retrievers (requires Neo4j 2026+)
retriever = VectorRetriever(
    driver=driver,
    index_name="chunk_embedding",
    embedder=embedder,
    use_search_clause=True,
)
```

---

## ORDER BY on Cypher Retrievers (v1.16.0)

```python
results = retriever.search(
    query_text="...",
    top_k=10,
    order_by="score DESC",
)
```

If `neo4j_schema=None`: retriever fetches schema automatically. For large schemas, pass a trimmed string to reduce LLM prompt size.

**Destructive-query guard [v1.16+]**: `Text2CypherRetriever` runs `EXPLAIN` on the generated Cypher before execution and rejects queries that produce writes (`CREATE`, `MERGE`, `DELETE`, `SET`, `REMOVE`, etc.). LLM-generated writes are never executed against the graph.


---

## Custom Prompt Template

```python
from neo4j_graphrag.generation.prompts import RagTemplate

template = RagTemplate(
    template="""Answer using ONLY the context below.
Context: {context}
Question: {query_text}
Answer:""",
    expected_inputs=["context", "query_text"],
)

rag = GraphRAG(retriever=retriever, llm=llm, prompt_template=template)
```

---

## return_context and response_fallback

```python
response = rag.search(
    query_text="...",
    retriever_config={"top_k": 5},
    return_context=True,                        # include raw retrieved chunks
    response_fallback="No relevant context.",   # skip LLM call if retriever returns nothing
)
print(response.answer)
print(response.retriever_result)    # RawSearchResult when return_context=True
```

---

## Message History (multi-turn)

```python
from neo4j_graphrag.message_history import InMemoryMessageHistory

history = InMemoryMessageHistory()
r1 = rag.search(query_text="Who is Alice?", message_history=history)
r2 = rag.search(query_text="Where does she work?", messa

Tools sind Metadatenhinweise, keine getestete Kompatibilität. Prompts sind Vorschläge.

Mit einer kleinen Aufgabe beginnen

  1. 1Quelle lesen und Eingaben, Ergebnisse, Abhängigkeiten sowie Berechtigungen prüfen.
  2. 2Agent um einen Plan bitten. Einrichtung und Kosten vor einem isolierten Test genehmigen.
  3. 3Ergebnisse und geänderte Dateien prüfen. Nur tatsächliche Ausführungen melden und die Quellrevision aufbewahren.

Prüfe Abhängigkeiten, API-Schlüssel und externe Kosten in der Quelle. Öffentliche Repositories bedeuten nicht, dass alle Dienste kostenlos sind.
