The Search element provides a graphical representation of the 'readall' expression and retrieves all rule object instances of a rule class which were created by client code. It can retrieve a single item from a list if the 'singleitem' expression is selected. The Search element can be added to other palette elements, for example, Filter or Create. No element can be added to the Search element.
