By adding the following to TextElement I was able to get search working:
@ContainedIn
private Document owner
Domanda
Here is a basic outline of my code:
@Entity
@Indexed
public class Document {
@IndexedEmbedded
@OneToMany(cascade = { PERSIST, MERGE }, mappedBy = "owner")
private final Set<Issue> issues = new LinkedHashSet<Issue>();
}
@Entity
public class Issue {
@ManyToOne
@JoinColumn(name = "owner_id")
@ContainedIn
private final Document owner;
@IndexedEmbedded
@OneToOne(cascade = ALL, optional = false)
@JoinColumn(name = "name_id")
@ForeignKey(name = "FK_issue__name_id__text_element")
private final TextElement name = new TextElement();
}
@Entity
public class TextElement {
@OneToMany(cascade = { CascadeType.ALL })
@JoinTable(
name = "text_element_paragraph",
joinColumns = { @JoinColumn(name = "text_element_id") },
inverseJoinColumns = { @JoinColumn(name = "paragraph_id") },
uniqueConstraints = {
@UniqueConstraint(
name = "UX_text_element_paragraph__paragraph_id",
columnNames = "paragraph_id"
)
}
)
@ForeignKey(
name = "FK_text_element_paragraph__text_element_id__text_element",
inverseName = "FK_text_element_paragraph__paragraph_id__paragraph"
)
@IndexedEmbedded
private List<Paragraph> paragraphs = new LinkedList<Paragraph>();
}
@Entity
public class Paragraph {
@Field(name = "data", analyze = Analyze.YES)
@Column(name = "s_data", nullable = false)
private String data;
}
I thought that lucene would be indexing the data in Paragraph, but when I open Luke it shows "issues.name.id" (id comes from a class Document extends). Why isn't the data be indexed? Thanks :)
I should also note that I just removed a manual indexer from the update method in the CRUD service. Everything stopped working after that, could it be something with my configurations?

I think all entities have to be annotated as @Indexed
, otherwise @IndexEmbedded
would not recognize entities to be indexed.
By the way: deep traversing may cause problems with re-indexing. You need to go the whole way back with @ContainedIn
