I am trying to make document index of the Entity that has following associations:

DocVersion:

@Entity

@Indexed

public class DocVersion implements Serializable {

...

    @ManyToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)

    @JoinColumn(name = "doc_uuid")

    @IndexedEmbedded

    private Document2 document2;

...

}

Document2:

@Entity

@Indexed

public class Document2 implements Serializable {

...

    @Column(name = "entityState")

    @Enumerated(EnumType.STRING)

    @Field(bridge=@FieldBridge(impl=EnumBridge.class), index=Index.YES)

    private EDocState eDocState;

...

}

this is how I query the index (just for testing purposes):

FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(entityManager);

        try {

            fullTextEntityManager.createIndexer().startAndWait();

        } catch (InterruptedException e) {

            e.printStackTrace();

        }



        QueryBuilder queryBuilder = fullTextEntityManager.getSearchFactory()

                .buildQueryBuilder()

                .forEntity(DocVersion.class)

                .get();



        org.apache.lucene.search.Query luceneQuery = queryBuilder.keyword()

                .onField("document2.eDocState").matching("HARD_DEL")

                .createQuery();

List results = fullTextEntityManager.createFullTextQuery(luceneQuery, DocVersion.class)

                .getResultList();

but instead of results I get:

WARNING: org.hibernate.search.bridge.BridgeException: Exception while calling bridge#objectToString

    entity class: com.nws.vedica.model.entity.DocVersion

    entity property path: document2.eDocState

    field bridge: TwoWayString2FieldBridgeAdaptor [stringBridge=org.hibernate.search.bridge.builtin.EnumBridge@60942b8b]

So what does that mean? Do I need to implement some specific bridge for an Enumeration (how would that look like)?
It's just value enum so I think problem is somewhere else.

Please assist me to get the results.

package I'm using:
hibernate-search-orm: 5.9.3.

You don't need to implement a specific bridge, actually it's quite the opposite: a bridge is already there, so Hibernate Search expects you to pass enum values to the query, and you're passing String values instead.

Try replacing .matching("HARD_DEL") with .matching(EDocState.HARD_DEL).

Note: I suspect the rest of the stack trace would tell you something about a class cast exception, which could have tipped you off. For your own sake, you should probably not hide stack traces like that, stack traces may contain valuable information.
