A multi-select attribute is an attribute that can be present on
records multiple times, with different values, in a single navigation state.
There are two forms of
multi-select attributes:
- If the navigation state
contains multiple values from a multi-select-and attribute, then all of the
records in that state contain all of the selected values for that attribute.
- If the navigation state
contains multiple values from a multi-select-or attribute, then all of the
records in that state contain at least one of the selected values.
This has consequences for the refinements that the Dgraph process of
the Oracle Endeca Server generates as well as the navigation state: the Dgraph
allows you to select additional values for a multi-select attribute.
In the Dgraph, you can configure an attribute as multi-select by
changing the values of the
system-navigation_Select attribute on the Property
Description Record for this attribute.
The multi-select feature is only fully supported for those attributes
(standard or managed) that do not contain a hierarchy.
