Search only works for terms without whitespace

Hibernate Search

I’m fairly new to Hibernate, so please tell me if I missed out on some information which you require.

My Problem is if I search for a description with 1 Term like “detailed” or “Description” I get a result, but if I keep a whitespace in between (“detailed Description”) I get no results, how would I accomplish this?

I have the following (shortend) Class “Part”

@Entity
@Indexed
public class Part {

@FullTextField(projectable = Projectable.YES)
private String description;

public String getDescription() {
    return description;
  }
  public void setDescription(String description) {
    this.description = description;
  }
}

And I have the following function inside a Dao Class

public List<Part> getParts() {
  EntityManager entityManager;
  SearchSession searchSession = Search.session(entityManager);
  ConvertToBean<List<?>, Part> converter = new ConvertToBean<List<?>, Part>(Part.class);
  return searchSession.search(Part.class).select( f -> f.composite(
          converter,
          f.field("description", String.class)
        ))
        .where(f -> f.bool(b -> {
            b.must(f.wildcard().field("description").matching(Util.withWildcard("detailed description")));
         })).fetchHits(1000)
  }

The persistence.xml includes all classes and the following properties

<properties>
            <property name="jboss.as.jpa.providerModule" value="application" />         
            <property name="hibernate.search.configuration_property_checking.strategy" value="ignore"/>
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
            <property name="hibernate.show_sql" value="true"/>
</properties>

Wildcard queries don’t (always) apply analysis, especially on Elasticsearch. Avoid them if you can.

See lucene - Hibernate Search: How to use wildcards correctly? - Stack Overflow for a solution that leverages analysis instead.

Thanks for the tips regarding wildcard queries.

The solution to my Problem was to simply use @GenericField(projectable = Projectable.YES) instead of @FullTextField(). The problem why it didn’t work when I tried it was, that my build task build the index before applying the new change.
