Ramesh Reddy commented on TEIID-3039:
-------------------------------------

I would prefer we do this work in V4, as spec is much more detailed about it here. Also gives us option to move users from V2 to V4. There is also "aggregations" extension to odata, we may have to get to after 8.11

As per the filtering, it can be on the expanded item like
{code}
http://host/service.svc/Customers?$expand=Orders($filter=Amount gt 100)
{code}

it can be multiple documents like (even nested)
{code}
http://host/service.svc/Orders?$expand=Items($expand=Product),Customer
{code}

or recursive
{code}
http://contoso.com/HR/Employees?$expand=Model.Manager/DirectReports($levels=4)
{code}

see this for more info [http://docs.oasis-open.org/odata/odata/v4.0/errata02/os/complete/part1-protocol/odata-v4.0-errata02-os-part1-protocol-complete.html#_Toc406398298]
