Examples of LuceneQueryResolverDelegate

org.hibernate.hql.lucene.internal.LuceneQueryResolverDelegate

This extends the ANTLR generated AST walker to transform a parsed tree into a Lucene Query and collect the target entity types of the query.
TODO:

It is currently human-written but should evolve into another ANTLR generated tree walker, not extending GeneratedHQLResolver but using its output as a generic normalization AST transformer.

We are assembling the Lucene Query directly, but this doesn't take into account parameter types which might need some transformation; the Hibernate Search provided {@code QueryBuilder} could do this.

Implement more predicates

Support multiple types being targeted by the Query

Support positional parameters (currently only consumed named parameters)

  private final QueryRendererProcessor rendererProcessor;

  public LuceneProcessingChain(SearchFactoryIntegrator searchFactory, EntityNamesResolver entityNames, Map<String, Object> namedParameters) {
    this.resolverProcessor = new QueryResolverProcessor( new LuceneQueryResolverDelegate( searchFactory, entityNames, namedParameters ) );


    LucenePropertyHelper propertyHelper = new LucenePropertyHelper( searchFactory );
    SingleEntityQueryBuilder<Query> queryBuilder = SingleEntityQueryBuilder.getInstance(
        new LucenePredicateFactory( searchFactory.buildQueryBuilder(), propertyHelper ),
        propertyHelper
