Restricting fields with @indexedEmbedded / includePaths

Hello,

I'm trying to restrict the fields indexed in a relation, it should be easy reading the doc.

Here's the model:

Code:

@Indexed
public class Client {
    @IndexedEmbedded
    private ProfessionnelGC professionnelGC;
}

Code:

@Indexed
public class ProfessionnelGC implements Serializable {
    @IndexedEmbedded(includePaths = { "raisonSociale" })
    private Groupe groupe;
}

Code:

@Indexed
public class Groupe  {

    @Field
    private String numeroContrat;

    @Field
    private String sapId;

    @Field
    private String raisonSociale;

}

I'd like to index only the "raisonSociale" field when indexing the parent (Client/ProfessionnelGC) entity, if i understood i should only have to give the name of the field (without prefix) in the includePaths annotation value, but it doesn't work.
If i don't use includePaths every sub field will be indexed, but as soon as i use includePaths nothing from the Groupe entity is indexed.
I tried every includePaths syntax (with or without part/full prefix etc), playing with prefix annotation value, no result.

If anybody can help, thanks a lot!

Hey,

I think you hit a bug there which shows up when it comes to multi-level hierarchies using @IndexedEmbedded. I've filed https://hibernate.atlassian.net/browse/HSEARCH-2194 for tracking it.

As a work-around you could specify just @IndexedEmbedded for ProfessionnelGC#groupe (that is, if you can live with all Groupe fields being added to the index of ProfessionnelGC) and then @IndexedEmbedded(includePaths = { "groupe.raisonSociale" }) on Client#professionalGC.

Thanks for the reply, right now i'm dealing with it by using non indexed AND non stored fields on solr.
Solr Schema is a bit polluted by those "ghosts" fields, and the data sent to solr is bigger than needed because of them but that's ok while waiting for a fix :)

Could you explain how Solr is integrated?

We have Solr support on our wishlist, but didn't implement it yet :)

With a custom BackendQueueProcessor implementation, using a basic HttpSolrServer instance (solrJ).
Started from this exemple, and made some cleanup/changes to use a newer solrJ version (4.1x needed for better pivot fields integration) and our specific needs.
