Migrating complex search from Hibernate Search 5 to 6

Hibernate Search
3

Another situation :frowning:
This won’t compile because I get this error:

Type mismatch: cannot convert from PredicateFinalStep to SearchPredicate

import org.hibernate.search.engine.search.predicate.SearchPredicate;
import org.hibernate.search.engine.search.predicate.dsl.SearchPredicateFactory;
import org.hibernate.search.mapper.orm.session.SearchSession;

// ...

SearchPredicateFactory pf = searchSession.scope( Article.class ).predicate();
List<SearchPredicate> predicates = new ArrayList<>();

// ... build the list of predicates ...

SearchPredicate classPredicate = pf.bool( b -> {
	for( SearchPredicate predicate : predicates ) {
		b.should( predicate );
	}
	b.minimumShouldMatchNumber( 1 );
} );

When I put a cast in front of pf.bool() the error is gone.
The example in migration guide does not have cast and I’m not sure I’m doing it right.
Since I have tons of code to convert, I’m not able to test it and I guess I won’t be able for days and days.

SearchPredicate classPredicate = (SearchPredicate) pf.bool( b -> {
	for( SearchPredicate predicate : predicates ) {
		b.should( predicate );
	}
	b.minimumShouldMatchNumber( 1 );
} );
