Limit is not recognized by query builder

[cleancoderocker]

In the code below not only five entities are returned, but all entities:

let cb = entityManager.getCriteriaBuilder();
let cq = cb.createQuery();
let operation = cb.equal('somename', 'somevalue');
let limit = 5;
let criteriaQuery = cq.where(operation, limit);
entityManager.findAll((error, result) => {}, criteriaQuery);  // Finds all entities
