I need help with a mapping (@IndexedEmbedded & @ContainedIn)

Hello,

I'm doing a searcher with Hibernate Search and I need to solve one question.

I have a main class: XxsgcExperts

Code:

@Indexed
public class XxsgcExperts implements java.io.Serializable {

   @DocumentId
   private BigDecimal idExperto;
   @ContainedIn
   private Set xxsgcPublicacioneses = new HashSet(0);
   @Field(index = Index.TOKENIZED, store = Store.NO)
   private String nombre;
   .....
   (rest o the bean)
}

that has some relactions as the next:

Code:

<set name="xxsgcPublicacioneses" table="XXSGC_PUBLICACIONES" inverse="true" lazy="true" fetch="select">
   <key>
      <column name="ID_EXPERTO" precision="22" scale="0" not-null="true" />
   </key>
   <one-to-many class="es.il3.sigec.model.beans.XxsgcPublicaciones" />
</set>

and the class XxsgcPublicaciones is here:

Code:

@Indexed
public class XxsgcPublicaciones implements java.io.Serializable {

   @DocumentId
   private BigDecimal idPublicacion;

   @IndexedEmbedded
   private XxsgcExperts xxsgcExperts;
   .....
   @Field(index = Index.TOKENIZED, store = Store.NO)
   private String tituloEs;
   @Field(index = Index.TOKENIZED, store = Store.NO)
   private String tituloCa;
}

I launch the indexer over XxsgcExperts and XxsgcPublicaciones and all it's ok, but I need do something that I don't know if it's possible.
I'd like to search from the XxsgcExperts to the fields of XxsgcExperts and XxsgcPublicaciones. This is, I need do something who

Code:

final MultiFieldQueryParser parser = new MultiFieldQueryParser(Version.LUCENE_30,"nombre,xxsgcPublicacioneses.tituloEs ", analyzer);

I've seen that with Luke, from XxsgcPublicaciones, you could search on XxsgcExperts fields, but I have to do the opposite and do not know if possible.

Thanks a lot and sorry for my english!!

Hi,
you have to change the mapping a bit: The indexed Document will containe the fields from the indexed entity + all fields following an @IndexedEmbedded. So just ass an @IndexedEmbedded annotation for the fields you want to add.

Hi,

I've tried with this code and doesn't works (Luke doesn't show XxsgcPublicaciones fields). Also, the indexing process has been slow to finish.

Code:

@Indexed
public class XxsgcExperts implements java.io.Serializable {

   @DocumentId
   private BigDecimal idExperto;
   @IndexedEmbedded
   private Set xxsgcPublicacioneses = new HashSet(0);
        ...

Thanks.

I´ve tried similar options as said in this page

viewtopic.php?p=2368543

but although the indexer takes such long time to do the process, the result is the same.

I can't believe that Hibernate can't do indexing with these options, although I imagine I'm doing something wrong and would be helpful for someone to help me.

Thanks a lot!

Hi,
there must be something wrong in some detail. It would really help if you could provide a working unit test I could look into. Please don't share a large project, just a functional tests.

There are examples of tests in our code base, have a look into existing tests at https://github.com/hibernate/hibernate-search
