Hibernate Search @IndexedEmbedded

Question

I have a similar situation like this one

@Entity
@Indexed
public class Place {
    @Id
    @GeneratedValue
    @DocumentId
    private Long id;

    @Field( index = Index.TOKENIZED )
    private String name;

    @OneToOne( cascade = { CascadeType.PERSIST, CascadeType.REMOVE } )
    @IndexedEmbedded
    private Address address;
    ....
}

@Entity
public class Address {
    @Id
    @GeneratedValue
    private Long id;

    @Field(index=Index.TOKENIZED)
    private String street;

    @Field(index=Index.TOKENIZED)
    private String city;

    @ContainedIn
    @OneToMany(mappedBy="address")
    private Set<Place> places;
    ...
}

The problem now is the following: If I change for example the name field in entity Place which entities are going to be re-indexed?

1) Only the name field?

2) The whole Place entity?

3) The whole Place entity and the entities annotated with @IndexedEmbedded?

The one I need for my purpose would be the third. So if it is not standard, could there be any solution to achieve this behaviour?

Fortunately it's really the third, so I was lucky and it works as expected

You can use the following code to re-index the Place Entity manually

public void updateIndex(T entity){
        FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(em);
        fullTextEntityManager.index(entity);
        fullTextEntityManager.getSearchFactory().optimize(entity.getClass());
    }

Secondly if you are using hibernate you can configure lucene in persistence.xml to automatically update the indexes of the entities that are changed

Actually that's not what I'm lookin for. I was interested in the automatic process

Can you give an example of this configuration?
