The objects that can be indexed are the objects that belong to a CBR-enabled class. An indexable class is a class that can be CBR-enabled.
The following base classes and subclasses of these classes are indexable:
String-valued properties of these classes are indexable as well. Note that for a string property to be indexed, both the class to which the property belongs and the property must be CBR-enabled. For example, for the FolderName property to be indexed, the Folder class and the FolderName property must be CBR-enabled.
