I am using OrientDB 2.2.17 (enterprise edition) and I have a problem searching on the data: 我正在使用OrientDB 2.2.17（企业版），但在搜索数据时遇到问题：

I have a vertex called: EN70 with a property: EP70_4 from type 'embedded list = LONG'. 我有一个名为：EN70的顶点，其属性为：'embedded list = LONG'类型的EP70_4。
I added a record to this vertex with the value of [2,3,4] in this 'EP70_4' property. 我在“ EP70_4”属性中为此值添加了一条记录，其值为[2,3,4]。
The index on this property: Not_Unique (sbtree). 该属性的索引：Not_Unique（sbtree）。 [must support range queries] [必须支持范围查询]
SELECT * FROM EN70 WHERE (EP70_4 >= 1) is working and returns my record. SELECT * FROM EN70 WHERE（EP70_4> = 1）正在工作并返回我的记录。
SELECT * FROM EN70 WHERE (EP70_4 <= 3) is working and returns my record. SELECT * FROM EN70 WHERE（EP70_4 <= 3）正在工作并返回我的记录。
The operator "Between" is not woking and throw exception: SELECT * FROM EN70 WHERE (EP70_4 BETWEEN 1 AND 3 ) 运算符“ Between”未唤醒并抛出异常：SELECT * FROM EN70 WHERE（EP70_4在1和3之间）
I tried to simulate a "between" operator: SELECT * FROM EN70 WHERE ((EP70_4 >= 1) AND (EP70_4 <= 3)) IS NOT WORKING but it is not working. 我试图模拟一个“介于”运算符：SELECT * FROM EN70 WHERE（（EP70_4> = 1）AND（EP70_4 <= 3））不起作用，但不起作用。

both sections 6 and 7 throws an exception: 第6节和第7节均引发异常：

Error on using index EN70.EP70_4 in query 'SELECT * FROM EN70 WHERE (EP70_4 BETWEEN 1 AND 3 )'. 在查询“ SELECT * FROM EN70 WHERE（EP70_4在1和3之间）”中使用索引EN70.EP70_4时出错。 Probably you need to rebuild indexes. 可能需要重建索引。 Now executing query using cluster scan java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.Long at
