The MDEX Engine's handling of multiselect-OR refinements has been improved.
Previously, dimensions were being labelled incorrectly as fully-implicit
dimensions and therefore were not being put in the
DimensionList returned by the Java
Navigation.getRefinementDimensions() and .NET
Navigation.RefinementDimensions calls. In 6.1.4, these
calls return fully-implicit multiselect-OR dimensions where at least one
selection has been made. This change also applies to the
Navigation.getRefinementDimGroups() and
Navigation.RefinementDimGroups calls.
In the context of this change, the definition of implicit refinements in the documentation has been updated to: Implicit refinements are refinements which, if selected, will not alter the navigation state record set.
To illustrate the multiselect-OR changes, assume a multiselect-OR dimension named PriceRange that has three dimension values and has the following sample data:
Dimension values: 10+ 20+ 30+ Data: productA, $5, () productB, $15, (10+) productC, $25, (10+, 20+) productD, $35, (10+, 20+, 30+)
This table shows the pre-6.1.4 and 6.1.4 results for various sample queries:
