symfony / doctrine configuration help

None of the functions are registered. I'm stuck on how to configure this correctly.

        $queryBuilder = $instanceRepository->createQueryBuilder('i')
            ->andWhere('CONTAINS(i.attributes, :attr)')
            ->setParameter('attr', 'year');

throw

assert($token !== null)

CONTAINS() needs = TRUE to work:

$queryBuilder = $instanceRepository->createQueryBuilder('i')
            ->andWhere('CONTAINS(i.attributes, :attr) = TRUE')
            ->setParameter('attr', 'year');
