hibernate怎么使用集合过滤？

在dao中有一个findAll方法，这个方法返回一个List集合，我想在这个返回的list的集合上运用hibernate的集合过滤功能，比如我想把这个集合中的所有对象的某个属性值小于3的过滤掉，其余的留在这个集合中返回给调用者，我的代码是这样写的：

dao 中的方法如下：

@SuppressWarnings("rawtypes")
    public List findAll() {
        Log.debug("finding all AdvanceQuery instances");
        try {
            Session session = this.getSession();
            String queryString = "from AdvanceQuery  a where a.frontNum = 0 order by a.cliCount desc";
            // String newQueryString =
            // PvgDataRoleUtil.querySqlFilter(queryString);
            System.out.println(queryString);
            Query queryObject = session.createQuery(queryString);
            return queryObject.list();
        } catch (RuntimeException re) {
            Log.error("find all failed", re);
            throw re;
        }
  
    }

测试方法如下：

public static void main(String[] args){
            AdvanceQueryDao advanceQueryDao = new AdvanceQueryDao();
            AdvanceQuery advanceQuery = new AdvanceQuery();
            List<AdvanceQuery> list = advanceQueryDao.findAll();
            for(AdvanceQuery advanceQuery2 :list){
                System.out.println(advanceQuery2.getCliCount());
            }
            Session session = HibernateUtil.getSession();
            Query query = session.createFilter(list,"where this.cliCount<3");
            List list1=query.list();
            for(int i = 0 ;i <list1.size();i++){
                AdvanceQuery advanceQuery2 = (AdvanceQuery)list1.get(i);
                System.out.println(advanceQuery2.getCliCount());
            }
      
    }

上述代码中的createFilter中的过滤条件其实是动态添加的，是不确定的，这只是一个例子，然后我运行代码时说这个集合没有被引用，怎么回事？

Hibernate: select advanceque0_.ID as ID1_11_, advanceque0_.FRONTNUM as FRONTNUM2_11_, advanceque0_.CLICOUNT as CLICOUNT3_11_, advanceque0_.TEMPLATENAME as TEMPLATENAME4_11_, advanceque0_.QUERYCLASSES as QUERYCLASSES5_11_, advanceque0_.LASQUERY as LASQUERY6_11_, advanceque0_.CLASSALIAS as CLASSALIAS7_11_, advanceque0_.DIAPLAIEDPRO as DIAPLAIEDPRO8_11_, advanceque0_.TEMLGROUP as TEMLGROUP9_11_, advanceque0_.NOTE as NOTE10_11_, advanceque0_.CREATEID as CREATEID11_11_, advanceque0_.LASTMODIFYID as LASTMODIFYID12_11_, advanceque0_.LASTMODIFYTIME as LASTMODIFYTIME13_11_, advanceque0_.CREATETIME as CREATETIME14_11_, advanceque0_.USERID as USERID15_11_ from ZCPLT_ADVANCEQUERY advanceque0_ where advanceque0_.FRONTNUM=0 order by advanceque0_.CLICOUNT desc
Exception in thread "main" org.hibernate.QueryException: The collection was unreferenced

我觉得可能是由于集合中的对象么有被持久化的原因，可是怎么给这个list中的对象持久化？
