Spring-data & Redis: sort the results - spring-boot

Question

From a Spring boot application, I want to use Redis and retrieve paged and sorted results.
Maven config:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>2.1.4.RELEASE</version>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.10.2</version>
<type>jar</type>
</dependency>
Based on an online example, I implemented the following repository:
#Repository
public interface StudentRepository extends PagingAndSortingRepository<Student, String> {
List<Student> findByName(String Name, Pageable page);
List<Student> findByName(String Name);
}
Now I want to filter my Student using
studentRepository.findAll(Sort.by("range").ascending());
With Student:
#RedisHash("Student")
public class Student implements Serializable {
#Id
private String id;
#Indexed
private String name;
private Gender gender;
private int grade;
Whatever the sort is, the order is always the same. After a debug session, I understood that the reason is:
class RedisQueryEngine extends QueryEngine<RedisKeyValueAdapter, RedisOperationChain, Comparator<?>> {
/**
* Creates new {#link RedisQueryEngine} with defaults.
*/
RedisQueryEngine() {
this(new RedisCriteriaAccessor(), null);
}
/**
* Creates new {#link RedisQueryEngine}.
*
* #param criteriaAccessor
* #param sortAccessor
* #see QueryEngine#QueryEngine(CriteriaAccessor, SortAccessor)
*/
private RedisQueryEngine(CriteriaAccessor<RedisOperationChain> criteriaAccessor,
#Nullable SortAccessor<Comparator<?>> sortAccessor) {
super(criteriaAccessor, sortAccessor);
}
The public constructor that is called by Spring has no sortAccessor defined. This sort accessor is then used in the QueryEngine class by my query:
public <T> Collection<T> execute(KeyValueQuery<?> query, String keyspace, Class<T> type) {
CRITERIA criteria = this.criteriaAccessor.map(it -> it.resolve(query)).orElse(null);
SORT sort = this.sortAccessor.map(it -> it.resolve(query)).orElse(null);
return execute(criteria, sort, query.getOffset(), query.getRows(), keyspace, type);
}
Is this behavior expected? Can Redis only page results (this works, I tested it) but not sort them (in this case, paging is totally useless)?
