About multi-select refinements

The Oracle Endeca Server supports two types of multi-select standard and managed attributes.

The default behavior of the Oracle Endeca Server permits only a single value from an attribute to be added to the navigation state. By default, after a user selects a leaf refinement from any managed attribute, that attribute is removed from the list of refinements available for future refinement in the query results. For example, after selecting "Apple" from the Flavors attribute, the Flavors attribute is removed from the navigation controls.

However, sometimes it is useful at navigation time to allow the user to select more than one value from an attribute. For example, you can give a user the ability to show wines that have a flavor of "Apple" and "Apricot".

The Oracle Endeca Server provides support for two types of multi-select standard and managed attributes that apply Boolean logic to the values selected:

You can tag the attribute as multi-and, or multi-or (or single) by changing the values of the system-navigation_Select attribute on the PDR that defines a particular attribute.
