 ## 🔍 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
 ```
