Spring-Data-Jpa + Hibernate-Search - Index not created

sinushyperbolikus · **Joined:** Tue Jun 16, 2015 11:05 am **Posts:** 4

I'm developing a Webapplication with Spring Boot and Spring Data Jpa with Hibernate. Due to the need of a full-text search capability I integrated the Hibernate Search Engine, but the Entities are not indexed unless I do a manual indexing by

fullTextEntityManager.createIndexer().startAndWait();

If I do the manual indexing of all Entities then everything works fine, but if I use the save()-Method of the CrudRepository then the index is not created.

Code:

public interface JobRepositoryCustom {
    public List<Job> searchJobs(SearchDto searchDto);
}

Code:

@Repository
public interface JobRepository extends  CrudRepository<Job, Integer>, JobRepositoryCustom {
}

Code:

public class JobRepositoryImpl implements JobRepositoryCustom {
    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public List<Job> searchJobs(SearchDto searchDto) {
        List<Job> jobs;
        FullTextEntityManager fullTextEntityManager = org.hibernate.search.jpa.Search.getFullTextEntityManager(entityManager);

        /*
        try {
            fullTextEntityManager.createIndexer().startAndWait();
        } catch (InterruptedException e) {
            System.out.println("An error occurred trying to build the serach index: " + e.toString());
        }*/

        QueryBuilder queryBuilder = fullTextEntityManager.getSearchFactory().buildQueryBuilder().forEntity(Job.class).get();

        org.apache.lucene.search.Query luceneQuery =   queryBuilder.bool().must(queryBuilder.keyword().onFields("title",  "introduction").matching(searchDto.getSearchTerm()).createQuery()).createQuery();

        org.hibernate.search.jpa.FullTextQuery fullTextQuery =    fullTextEntityManager.createFullTextQuery(luceneQuery, Job.class);

        jobs = fullTextQuery.getResultList();

        return jobs;
    }
}

I have searched the whole Internet for a solution and I appreciate every assistance. Thanks

You can only query the changes after the transaction was committed. Are you saving things within the same transaction which is performing the query?

Hi, I'm not saving the entities within the same transaction which is performing the query. The entities are saved by a service layer class which is using a Crudrepository and invocating the save method on it. Crudrepo methods are transactional by default in spring data jpa.

Ok, I tried to guess with the most common misunderstandings I've seen for such a problem.

Another thing I would suggest to verify is to see if your transaction manager is configured correctly: that's another common problem with Spring users. Or simply debug it and try to see why the indexing events are not being applied.

I'm sorry I don't have other ideas, but I'm pretty sure this is just configuration issue.

Spring-Data-Jpa is doing the transaction management by default and automatically. I don't exactly know what to configure at the transaction manager. How to debug it?

Hi,

I've solved the problem. I'm using an h2 database which stores the data in a file after the application is stopped and I forgot to cleanup the database files.
