Hibernate Search with Spring Boot 3

I'm using spring boot v3.1.2. I'm trying to implement the search feature using Hibernate search with Lucene. For the configuration, I followed the following documentation

I'm struggling bcz manything have been changed in the latest versions of Hibernate Search ! the searchByQuery returns an empty list even though I expect data to match the query

@RequiredArgsConstructorpublic class ProductRepositoryImpl implements ProductRepository {    private final EntityManager entityManager;    @Override    public List<Product> searchByQuery(String query, Pageable pageable) throws RuntimeException {        SearchSession searchSession = Search.session( entityManager );        SearchResult<Product> result = searchSession.search( Product.class )                .where( f -> f.match()                        .fields( "title", "description" )                        .matching( query ) )                .fetch( 20 );        long totalHitCount = result.total().hitCount();        List<Product> hits = result.hits();        return hits;    }}

I suspect that the data hasn't been indexed yet ! any insights on what I might have overlooked ?

// Product.javaimport org.hibernate.search.mapper.pojo.mapping.definition.annotation.FullTextField;import org.hibernate.search.mapper.pojo.mapping.definition.annotation.Indexed;@Table(name = "products")@Getter@Setter@Builder@AllArgsConstructor@NoArgsConstructor@EqualsAndHashCode@Indexedpublic class Product extends BaseEntity {    @Id    @GeneratedValue(strategy = GenerationType.IDENTITY)    private Integer id;    @FullTextField    private String title;    private String code;    @FullTextField    private String description;    ...
