Why Hibernate Search indexing not working properly
I've integrated Hibernate Search to my backend for Full Text Search,
The application works fine, I added some info to my database(see the screenshots) but when I search for a word sometimes (word="1") I only get one result instead of multiple results, sometimes(for an other word "ex: maroc") I don't get anything. I think it's an indexing problem not a query problem.
This is my Entity code:
import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.hibernate.search.annotations.*;
import javax.persistence.*;;
import java.util.Set;
@Entity
@Indexed
@Table(name="client")
public class Client {
@Id
@Column(name="id")
@GeneratedValue(strategy=GenerationType.AUTO)
private long id;
@Column(name="fullname")
@Field(termVector = TermVector.YES,analyzer = @Analyzer(impl = StandardAnalyzer.class))
String fullName;
@Column(name="adress")
@Field
String adress;
This is my SearchService code:
import org.apache.lucene.search.Query;
import org.hibernate.search.jpa.FullTextEntityManager;
import org.hibernate.search.jpa.Search;
import org.hibernate.search.query.dsl.QueryBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.NoResultException;
import java.util.List;
@Component
public class SearchService {
@Autowired
private EntityManager entityManager;
@Autowired
public SearchService( EntityManagerFactory entityManagerFactory) {
super();
this.entityManager = entityManagerFactory.createEntityManager();
}
public void initializeHibernateSearch() {
try {
FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(entityManager);
fullTextEntityManager.createIndexer().startAndWait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
@Transactional
public List<Client> clientSearch(String searchTerm) {
FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(entityManager);
QueryBuilder qb = fullTextEntityManager.getSearchFactory().buildQueryBuilder().forEntity(Client.class).get();
Query luceneQuery = qb.keyword().fuzzy().withEditDistanceUpTo(1).withPrefixLength(1).onFields("id","adress","fullName")
.matching(searchTerm).createQuery();
javax.persistence.Query jpaQuery = fullTextEntityManager.createFullTextQuery(luceneQuery, Client.class);
// execute search
List<Client> clientList = null;
try {
clientList = jpaQuery.getResultList();
} catch (NoResultException nre) {
}
return clientList;
}
This is my HibernateSearchConfiguration code:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.persistence.EntityManagerFactory;
@Configuration
@EnableAutoConfiguration
public class HibernateSearchConfiguration {
private EntityManagerFactory entityManagerFactory;
@Autowired
public HibernateSearchConfiguration(EntityManagerFactory entityManagerFactory) {
this.entityManagerFactory = entityManagerFactory;
}
@Bean
SearchService hibernateSearchService() {
SearchService hibernateSearchService = new SearchService(this.entityManagerFactory);
hibernateSearchService.initializeHibernateSearch();
return hibernateSearchService;
}
}
that's the error in the terminal btw:

Solution
Alright, the stacktrace changes everything. The problem is not in your mapping.
See this:
2020-05-05 13:21:11,084 ERROR org.hibernate.search.exception.impl.LogErrorHandler : HSEARCH000058: HSEARCH000117: IOException on the IndexWriter

Hibernate Search failed to obtain a lock to the index writer. This can happen in two cases:
- Your application was stopped (very) brutally and didn't release the lock. In this case, the easiest solution is to delete everything and reindex, because it's likely you lost some data when the application was stopped brutally.
- You're attempting to use the same index from two separate instances of your applications. If you really need to do this, you should consider relying on Elasticsearch instead of a local Lucene index; see here.
