## 🔍 Repository Query Methods

Spring Data FalkorDB supports JPA-style query methods with these patterns:
Spring Data FalkorDB supports two types of queries:

### 1. Derived Query Methods (Automatically Implemented)

Define methods following Spring Data naming conventions, and the implementation is generated automatically:

### Query Keywords
#### Query Keywords

- **`findBy...`**: Find entities matching criteria
- **`countBy...`**: Count entities matching criteria
- **`existsBy...`**: Check if entities exist matching criteria
- **`deleteBy...`**: Delete entities matching criteria
- **`findFirstBy...`** / **`findTopNBy...`**: Limit results

### Supported Operations
#### Supported Comparison Operations

```java
// Exact match
// Equality
findByName(String name)
findByNameNot(String name)

// Comparison operations
// Comparison
findByAgeGreaterThan(int age)
findByAgeGreaterThanEqual(int age)
findByAgeLessThan(int age)

// Range queries
findByAgeBetween(int start, int end)
findByAgeLessThanEqual(int age)

// String operations
findByNameContaining(String substring)
findByNameStartingWith(String prefix)
findByNameIgnoreCase(String name)
findByNameContaining(String substring) // *substring*
findByNameStartingWith(String prefix) // prefix*
findByNameEndingWith(String suffix) // *suffix
findByNameLike(String pattern) // Custom pattern
findByNameNotContaining(String substring)

// Null checks
findByEmailIsNull()
findByEmailIsNotNull()

// Boolean
findByActiveTrue()
findByActiveFalse()

// Collections
findByAgeIn(Collection<Integer> ages)
findByAgeNotIn(Collection<Integer> ages)

// Logical operations
findByNameAndAge(String name, int age) // AND condition
findByNameOrEmail(String name, String email) // OR condition

// Sorting and pagination
findAllByOrderByNameAsc()
findByAgeGreaterThan(int age, Sort sort)
findByAgeGreaterThan(int age, Pageable pageable)

// Logical operations
findByNameAndAge(String name, int age)
findByNameOrEmail(String name, String email)
// Limiting results
findFirstByOrderByCreatedAtDesc()
findTop10ByOrderByAgeDesc()
```

### 2. Custom Cypher Queries with @Query

Write custom Cypher queries for complex operations:

```java
public interface PersonRepository extends FalkorDBRepository<Person, Long> {

// Using named parameters
@Query("MATCH (p:Person)-[:KNOWS]->(f:Person) "
+ "WHERE p.name = $name RETURN f")
List<Person> findFriends(@Param("name") String name);

// Using indexed parameters
@Query("MATCH (p:Person) WHERE p.age > $0 RETURN p")
List<Person> findOlderThan(int age);

// Count query
@Query(value = "MATCH (p:Person)-[:WORKS_FOR]->(c:Company) "
+ "WHERE c.name = $company RETURN count(p)",
count = true)
long countEmployees(@Param("company") String company);

// Exists query
@Query(value = "MATCH (p:Person {email: $email}) RETURN count(p) > 0",
exists = true)
boolean emailExists(@Param("email") String email);

// Write query (creates/updates data)
@Query(value = "MATCH (p:Person {id: $id}) "
+ "SET p.lastLogin = $time",
write = true)
void updateLastLogin(@Param("id") Long id, @Param("time") LocalDateTime time);
}
```

### Query Method Examples

```java
// Simple equality
List<Person> people = repository.findByName("John");

// Comparison
List<Person> adults = repository.findByAgeGreaterThanEqual(18);

// String matching
List<Person> smiths = repository.findByNameEndingWith("Smith");

// Logical AND/OR
List<Person> results = repository.findByNameAndAgeGreaterThan("John", 25);
List<Person> results = repository.findByNameOrEmail("John", "[email protected]");

// Null checks
List<Person> noEmail = repository.findByEmailIsNull();

// Collections
List<Person> youngPeople = repository.findByAgeIn(Arrays.asList(18, 19, 20));

// Counting and existence
long count = repository.countByAge(25);
boolean exists = repository.existsByEmail("[email protected]");

// Sorting
List<Person> sorted = repository.findByAgeGreaterThan(20, Sort.by("name").ascending());

// Pagination
Page<Person> page = repository.findByAgeGreaterThan(18, PageRequest.of(0, 10));

// Limiting
Optional<Person> youngest = repository.findFirstByOrderByAgeAsc();
List<Person> oldest = repository.findTop5ByOrderByAgeDesc();

// Delete
repository.deleteByAge(0); // Delete all with age = 0
```

⚠️ Potential issue | 🔴 Critical

🧩 Analysis chain

Verify implementation status claims match actual code.

The "Fully Implemented & Tested" section makes extensive claims about feature completeness. Ensure that unit and integration tests validate these capabilities, especially for all the query operators and projections listed.

Run the test suite to confirm coverage of the listed features:


🏁 Script executed:

#!/bin/bash
# Verify test coverage for derived query methods and @Query support

echo "=== Searching for tests of derived query operations ==="
rg -n --type=java -A3 "findBy.*GreaterThan|findBy.*LessThan|findBy.*Containing|countBy|existsBy|deleteBy" src/test/

echo "=== Searching for tests of @Query annotation ==="
rg -n --type=java -A3 "@Query.*value.*=.*MATCH" src/test/

echo "=== Searching for integration tests ==="
fd -e java -x grep -l "Integration.*Test" {} \; | head -10

Length of output: 9025


I can see repository interface definitions with derived queries and @query annotations, but I need to verify actual test implementations that exercise these features. Let me search for the test methods themselves.

Let me search for the actual test method implementations in the integration test file:

Let me directly inspect the integration test file to verify actual test implementations:


🏁 Script executed:

#!/bin/bash
# Look for actual @Test methods that call repository methods

echo "=== Inspecting FalkorDBTwitterIntegrationTests for @Test methods ==="
cat src/test/java/org/springframework/data/falkordb/integration/FalkorDBTwitterIntegrationTests.java | grep -A 20 "@Test"

echo ""
echo "=== Checking for test count and method names ==="
rg -n "@Test" src/test/java/org/springframework/data/falkordb/integration/FalkorDBTwitterIntegrationTests.java

Length of output: 2560


Let me check the helper methods to see if they actually test the derived query methods and @query capabilities:


🏁 Script executed:

#!/bin/bash
# Look for helper method implementations and what they call

echo "=== Searching for testGraphTraversalQueries implementation ==="
rg -n "testGraphTraversalQueries|testRelationshipQueries|testAnalyticsQueries" src/test/java/org/springframework/data/falkordb/integration/FalkorDBTwitterIntegrationTests.java -A 15

I found a critical issue: the integration tests use raw Cypher queries via falkorDBOperations, not the repository methods. Let me check if there are other test files that actually test the derived query methods and @query support:


🏁 Script executed:

#!/bin/bash
# Search for any test file that calls derived repository methods

echo "=== Searching for test files that call repository methods ==="
rg -l "findBy|countBy|existsBy|deleteBy" src/test/java --type=java

echo ""
echo "=== Searching for @Test methods calling repository methods ==="
rg -n "@Test" -A 20 src/test/java --type=java | grep -E "(@Test|findBy|countBy|existsBy|deleteBy|@Query)" | head -40

echo ""
echo "=== Checking PersonRepository test file ==="
fd -e java -path "*test*" -name "*Person*Test*" -o -path "*test*" -name "*PersonRepository*Test*"

Length of output: 2875


Let me inspect the actual test implementations in AnnotationUsageTests and RelationshipMappingTests:


🏁 Script executed:

#!/bin/bash
# Get full implementation of AnnotationUsageTests

echo "=== AnnotationUsageTests.java @Test methods ==="
cat src/test/java/org/springframework/data/falkordb/examples/AnnotationUsageTests.java

echo ""
echo "=== RelationshipMappingTests.java full content ==="
cat src/test/java/org/springframework/data/falkordb/examples/RelationshipMappingTests.java

Length of output: 11770


Add integration tests validating all claimed derived query and @query capabilities.

The repository interface definitions exist (TwitterUserRepository, PersonRepository, MovieRepository) with methods for all listed operators and projections, but the test suite does NOT exercise them. Both FalkorDBTwitterIntegrationTests and AnnotationUsageTests bypass repository methods entirely—using raw Cypher queries or providing only documentation. Grep search confirms zero calls to findBy*, countBy, existsBy, deleteBy, or @Query methods in any test.

Create integration tests that call repository methods for:

  • Derived queries: findByFollowerCountGreaterThan, findByDisplayNameContaining, etc.
  • Query projections: countFollowing, countFollowers
  • @query methods with named/indexed parameters
  • Count, exists, and write operation projections
