Lucene query on @indexedEmbedded objects id

Question

Im trying to use a org.apache.lucene.search.Query to fetch all entries with a Object @indexedEmbedded with a certain @id id. This simply does not work with my current code. My code as follows:

The Search

FullTextSession fullTextSession = getFullTextSession();
QueryBuilder queryBuilder = fullTextSession.getSearchFactory().buildQueryBuilder().forEntity(Request.class).get();

org.apache.lucene.search.Query query = queryBuilder.keyword()
                .onField("keyword.id")
                .matching(keywordId)
                .createQuery();

FullTextQuery fullTextQuery = fullTextSession
                .createFullTextQuery(query, Request.class);

return fullTextQuery.list();

Request.class

@Entity
@Indexed
public class Request etc etc..

    @ManyToOne
    @IndexedEmbedded
    private Keyword keyword;

Keyword.class

@Entity
@Indexed
public class Keyword etc etc..

    @Id
    @GeneratedValue
    private Long id;

I don't receive any errors when executing this code, the result just isn't restricted to the Request objects with a keyword with the supplied id.

I use this in junction with a org.apache.lucene.search.BooleanQuery later on, but even when trying this itself it doesn't work. I'm aware that this might be the wrong approach so any suggestions would be appreciated.

Thanks!

The indexing properties was not set properly, the index of the request class was simply not indexed as it should have been. Added following code to fix the misstake:

<property name="hibernateProperties">
    <props>
        ...
        <prop key="hibernate.search.default.indexBase">/var/lucene/indexes</prop>
        <prop key="hibernate.search.default.directory_provider">filesystem</prop>
        <prop key="hibernate.search.lucene_version">LUCENE_CURRENT</prop>
    </props>
</property>
