 A Query is defined for a single [[MetaClass]], where the MetaClass is defined in the property '''FILTEROBJECT'''. Once a query is evaluated it will deliver a list of objects of type ContentClasses (instances), filtered as defined by its [[QUERYITEM|QueryItems]].
 The correspondence between Queries and its items is created and stored by a relationship [[SYSREL_QUERY]]. Therefore a single QueryItem can be used several times for different Queries.
