Filter 具有多个联接的Dynamics CRM查询表达式，添加筛选器或条件创建不返回结果

//下面的代码产生了问题，如果我删除它，它会工作，我会 结果。但我需要添加两个过滤器

---

如果我用custFilter或childFilter删除所有条件，我会得到结果，但当我保留这两个条件时，它会返回任何结果（无错误）。

下面的调整解决了我的问题

                custFilter.AddCondition("name", ConditionOperator.Equal, SearchText);
                custFilter.AddCondition("den_firstname", ConditionOperator.Equal, SearchText);
                //custFilter.AddCondition("den_lastname", ConditionOperator.Equal, SearchText);
                custFilter.AddCondition("emailaddress1", ConditionOperator.Equal, SearchText);
                custFilter.AddCondition("telephone1", ConditionOperator.Equal, SearchText);
            }

您是得到一个错误还是只得到0个结果？若一次添加一行有问题的过滤器会怎么样？我得到0个结果，并没有任何错误。我假设两个条件都与AND运算符一起使用，而我的意图是使用OR运算符。

                custFilter.AddCondition("name", ConditionOperator.Equal, SearchText);
                custFilter.AddCondition("den_firstname", ConditionOperator.Equal, SearchText);
                //custFilter.AddCondition("den_lastname", ConditionOperator.Equal, SearchText);
                custFilter.AddCondition("emailaddress1", ConditionOperator.Equal, SearchText);
                custFilter.AddCondition("telephone1", ConditionOperator.Equal, SearchText);
