Using “BETEEN” operator on a LONG-EMBEDDED-LIST property declared in OrientDB 2.2.17

Question

I am using OrientDB 2.2.17 (enterprise edition) and I have a problem searching on the data:

1. I have a vertex called: EN70 with a property: EP70_4 from type 'embedded list = LONG'.

2. I added a record to this vertex with the value of [2,3,4] in this 'EP70_4' property.

3. The index on this property: Not_Unique (sbtree). [must support range queries]

4. SELECT * FROM EN70 WHERE (EP70_4 >= 1) is working and returns my record.

5. SELECT * FROM EN70 WHERE (EP70_4 <= 3) is working and returns my record.

6. The operator "Between" is not woking and throw exception: SELECT * FROM EN70 WHERE (EP70_4 BETWEEN 1 AND 3 )

7. 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.

both sections 6 and 7 throws an exception:

Error on using index EN70.EP70_4 in query 'SELECT * FROM EN70 WHERE (EP70_4 BETWEEN 1 AND 3 )'. Probably you need to rebuild indexes.
