Currently when the setting compass.osem.supportUnmarshall is set to false, calling CompassHits.data() will still cause unmarshalling to occur. It is implicitly assumed that CompassHits.resource() will get called instead to retrieve the properties stored in the index. A couple of options were presented on the mailing list to address this problem: 1. Have the ability to get the id object from the resource (if possible). 2. Have data return the object instance with only its id initialized. The second option would be nice because Hibernate needs both the class and id to load the object, and I have not yet found an elegant way to get the class given just the data available from CompassHits.resource(). It would also be nice to be able to turn the supportUnmarshall setting off and not have to change the way search hits are retrieved.
