-- Setup: create test graph and set as current
CALL create_test_graph_data('g', 10);
SESSION SET GRAPH g;

-- Test 1: Simple property equality filter on single vertex
MATCH (p:PERSON) WHERE p.name = 'person0' RETURN p;

-- Test 2: Multi-hop with filter on target vertex
MATCH (p:PERSON)-[w:WORKS_AT]->(c:COMPANY) WHERE c.name = 'company0' RETURN p, w, c;

-- Test 3: Filter on source vertex in a path
MATCH (p:PERSON)-[w:WORKS_AT]->(c:COMPANY) WHERE p.name = 'person0' RETURN p, w, c;

-- Test 4: Comparison filter (age > value)
MATCH (p:PERSON) WHERE p.age > 22 RETURN p;

-- Test 5: Return only a property with filter
MATCH (p:PERSON) WHERE p.age > 22 RETURN p.name;

-- Test 6: Filter with no matching rows
MATCH (p:PERSON) WHERE p.name = 'nonexistent' RETURN p;

-- Test 7: Two-hop path with filter on source vertex
MATCH (p:PERSON)-[f:FRIEND]->(p2:PERSON)-[w:WORKS_AT]->(c:COMPANY) WHERE p.name = 'person0' RETURN p, p2, c;
