Quick sample here. Let’s say you want to get all the service requests assigned to a particular support group (enum data type property). No problem! Use ObjectProjectionCriteria . That will get you projection objects. If you want to just get objects you can use the related EnterpriseManagementObjectCriteria class. ( what is a type projection/projection objects? )
Here are some more details:

Here are some examples that people have put out on the web.

Party on!
