Hi,

I have a problem getting indexing to work, and I'm having a hard time diagnosing the reason. Automatic indexing fails. When I add a manual indexing action to the dao save action, I can trace to the point where the indexing work action is added to a post transaction queue.

However, the index doesn't get added. I'm wondering how to diagnose my problem. I'm thinking I have a configuration problem that doesn't throw an error

The class in question is a non abstract mother to child classes. I can see several Warnings during startup

Hibernate version:
Hibernate Search 3.1.0, Hibernate Core 3.3.1, Spring 2.5.6, Appfuse 2.0.2



WARN [main] DocumentBuilderContainedEntity.checkDocumentId(409) | @DocumentId specified on an entity which is not indexed by itself. Annotation gets ignored. Use @Field instead.


I have traced these to the child classes for the mother classes which have not been annotated for indexing.

My class looks like this:

@Entity
@Table(name = "Offers")
@Inheritance(strategy = InheritanceType.JOINED)
@Indexed
@FullTextFilterDefs( {
@FullTextFilterDef(name = "offerTerms", impl = OfferFilterFactory.class),
@FullTextFilterDef(name = "validUntil", impl = RangeFilterFactory.class) })
public class Offer implements Serializable{

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "offerID", updatable = false, insertable = false)
@DocumentId
public Long getId() {
return id;
}

@Column
@Field(index = Index.TOKENIZED, store = Store.YES)
public String getTitle() {
return title;
}

@Field(index = Index.TOKENIZED, store = Store.YES)
@Boost(2.5f)
public String getDescription() {
return description;
}

@ManyToOne(optional = true, cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinColumn(name = "FK_PhotoID", nullable = true, updatable = true)
@IndexedEmbedded
public Photo getPhoto() {
return photo;
}

@Column
@Field(store = Store.YES, index = Index.TOKENIZED)
public Date getEntryDate() {
return entryDate;
}

@ManyToOne(optional = false, cascade = CascadeType.MERGE, fetch = FetchType.LAZY)
@JoinColumn(name = "FK_CategoryID", nullable = true, updatable = true)
@IndexedEmbedded(depth = 2)
public Category getCategory() {
return category;
}

@OneToOne(optional = false, cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinColumn(name = "FK_ValidityID",nullable=false,updatable=false)
@IndexedEmbedded
public Validity getValidity() {
return validity;
}

[...]

}

Any ideas?

Hi,

the annotations look ok - at least when it comes to the Offer class. The warning probably comes from the fact that one of the @IndexedEmbedded classes contains a @DocumentId even though the class itself is not indexed.

Is there anything else in the log file? How does your indexing code look like? Are you sure that your transaction management works properly. You are mentioning that you are using Spring. Are you using the HibernateTemplate or do you use declarative transaction management. I think it would help to see how the code between a transaction/session open and close looks like.

Some general comments. Since you are using annotations you don't need @DocumentId. @Id will automatically be selected as document id. You should also not have to register the event listeners explicitly. Neither in hibernate.cfg.xml nor in persistence.xml. hibernate.search.autoregister_listeners="true" is also the default and should not be needed.

Are the actual index directories actually created when you start the application?

Hi and thanks for your reply. To answer your questions:
I had removed all of indexEmbedded annotations. I personally think the warnings come from the child classes for the non-abstract Offer which don't have @DocumentId references.

The indexing code. I have tried the following:


I tried with and without fts.index(off). Autoindexing should not required the index action, right?

That's about it. I dont see anything special in the logs referring to this.
Yes, the index directories get created.

I will try to remove those event elements and the other suggestions you made.

I would appreciate a head's up if you see any issues in my code.

Thanks

Marc

Hi,

as far as I can see it should be ok. And you should need the explicit indexing. Are you saying it actually works when you are using the explicit indexing and it's not working without?

I have seen several post where the problem was the transaction support. You can configure your application to output spring transaction logging. This way you can see when a transaction gets created and commited. Are the changes properly persisted in the database?

You could also set the log4j category for [i]org.hibernate.search.backend.impl.lucene.works[i] to trace. You should then see something like 'add to Lucene index ...' when an entity gets indexed.

BTW, how do you know that indexing does not work? Do you run a query? Or do you use Luke to inspect the index?
