用于一次搜索表的三列的Hibernate查询

我正在尝试通过Hibernate查询语言在表的三列中搜索字符串的一部分。但是我的代码工作不正常。我假设我的查询无效。这是我的代码：

public AccountList findAccounts(String check) {    
        Query query = em.createQuery("SELECT a FROM Account a"
                + "WHERE a.username LIKE ?1 "
                +"OR a.namefirst LIKE ?1 "
                +"OR a.namelast LIKE ?1");
        query.setParameter(1, "%"+check+"%");
        List accounts = query.getResultList();;
        if (accounts.size() == 0) {
            return null;
        } else {
            return new AccountList(accounts);
        }
    }

有人可以告诉我如何一次搜索三列。当我只搜索一列时，我的代码就可以工作。这是我的堆栈跟踪。

Query query = em.createQuery("SELECT a FROM Account a"
        + "WHERE a.username LIKE ?1 "
        +"OR a.namefirst LIKE ?1 "
        +"OR a.namelast LIKE ?1");
  

意外令牌：近线1，第55栏[SELECT a FROM web.core.models.entities.Account aWHERE a.username LIKE？1或a.namefirst LIKE？1或a。 namelast LIKE？1]

“a”和“where”之间没有空格，因为查询的第一行以“a”结束，下一行以“where”开头。
