Bug: Notebook 05 full text search

[JakobEliasWagner]

Bug: Session.run() gets multiple values for query in notebook 05

Summary

Notebook 05 full-text search crashes with:
TypeError: Session.run() got multiple values for argument 'query'

Repro

Run this cell after following the prior notebook setup:

def fulltext_search(driver, index_name, query: str, top_k=5):
    """Perform a full-text search and display results."""
    with driver.session() as session:
        result = session.run("""
            CALL db.index.fulltext.queryNodes($index, $query)
            YIELD node, score
            RETURN node, score, labels(node) AS labels
            LIMIT $limit
        """, index=index_name, query=query, limit=top_k)
        return list(result)

# Basic search: find chunks mentioning "thermal"
query = "thermal"
print(f'Search: "{query}"')
print("=" * 60)

results = fulltext_search(driver, 'requirement_text', query)
for i, record in enumerate(results):
    node = record['node']
    text = node.get('text', node.get('name', 'N/A'))
    print(f"\n[{i+1}] Score: {record['score']:.4f}")
    print(f"    {str(text)[:150]}...")

Error

TypeError: Session.run() got multiple values for argument 'query'

Cause

session.run(, query=...) conflicts with the driver’s run(query, ...) signature (query is the Cypher string parameter name).

Fix

Rename the Cypher parameter and the kwarg (e.g., $q / q=):

def fulltext_search(driver, index_name, query, top_k=5):
    """Perform a full-text search and display results."""
    with driver.session() as session:
        result = session.run("""
            CALL db.index.fulltext.queryNodes($index, $q)
            YIELD node, score
            RETURN node, score, labels(node) AS labels
            LIMIT $limit
        """, index=index_name, q=query, limit=top_k)
        return list(result)
