Hibernate : Criteria giving null back for disjunction, even though data exists with matching params

I am working on a Spring-MVC project in which I am using Hibernates Criteria functionality for search. Currently, for testing I am trying out the search code with disjunction. Even with it, I am getting null back from the criteria query. I have added 5000 random rows and if nothing atleast the boolean values match in the database. But I don't have results. Any ideas?

Code :

@Override
    public List<Student> getRecommendedStudents(Host host) {
        Session session = this.sessionFactory.getCurrentSession();
        Criteria andCriteria = session.createCriteria(Student.class);
        Disjunction and = Restrictions.disjunction();
        if ((host.getCity() != null) && (!(host.getCity().isEmpty()))) {
            and.add(Restrictions.ilike("city", host.getCity()));
        }
        if ((host.getGender() != null) && (!(host.getGender().isEmpty()))) {
            and.add(Restrictions.ilike("gender", host.getGender()));
        }
        if ((host.getMotherTongue() != null) && (!(host.getMotherTongue().isEmpty()))) {
            and.add(Restrictions.ilike("motherTongue", host.getMotherTongue()));
        }

        if (host.getOtherLanguages() != null) {
            if (!(host.getOtherLanguages().isEmpty())) {
                and.add(Restrictions.in("otherLanguages", host.getOtherLanguages()));
            }
        }
        and.add(Restrictions.eq("drivingLicense", host.isDrivingLicense()));
        and.add(Restrictions.eq("smoker", host.isWeSmoke()));
        and.add(Restrictions.eq("previouslyAuPair", host.isPreviousAuPair()));
        and.add(Restrictions.eq("willingToWork", host.isHouseWork()));
        and.add(Restrictions.eq("workForSingleParent", host.isSingleParent()));
        and.add(Restrictions.eq("workingForDisabledChild", host.isChildAssistance()));
        andCriteria.add(and);
        return andCriteria.list();
    }

I don't have any errors, just no results. Thank you.
