I'm trying to return a query where the filter includes a collection of records identified by ID. The collection will have been chosen by the user, so there's no way to predict the sequence. The only way I could see this happening is if I called a service operation and then called the Query.

 I understand that you may have technical issuing in the get for the collection parameters, but I would have thought this a common requirement.

What's the suggested approach?

Thanks.
