Remarks
The derived properties collection consists of properties whose values are the result of
applying a function to each constituent record that is aggregated by this
AggregateRecord. For example, if the records in MDEX engine represent
books, then an AggregateRecord might have a derived property that is
calculated by applying the MIN function to each constituent record. The value
representing the minimum price can then be read from the PropertyMap
returned from this method.
Derived properties may be configured by editing the Derived_props.xml file. Please refer to the Endeca Developer's Guide for further details.
