How to Pass Multiple Value Range From Query ?

Hi,

I have searched over SDN to find about how do we pass multiple value ranges from Query to SAP ODATA?

But I have not found suitable answers so I am posting it here.

If we need to pass a date parameter in Query which has a multiple range like  sales orders created date between 03/02/2014 to 05/07/2014.

How do we phrase it in Query ?

I tried as below but the IT_FILTER_SELECT_OPTIONS of /IWBEP/IF_MGW_APPL_SRV_RUNTIME~GET_ENTITYSET does not get filled up with the parameters

How do we pass multiple values in Query?

Thanks in Advance.
