Guided Navigation

The Guided Navigation component provides Endeca Guided Navigation® functionality.

The Guided Navigation component provides contextual navigation across large volumes of structured MDEX Engine-specific data. End users can expand and close multiple dimension groups, view dimension values from multiple dimensions at a time, and select multi-OR and multi-AND dimensions. End users can also apply negative refinements to exclude dimension values from results if negative refinements are enabled by the power user.

The component shows the dimension groups that are configured in the MDEX Engine. It also displays base refinement statistics if they are enabled in the MDEX Engine.

Note: Contracted or implicit dimension values and dead ends are not shown in this component.

The Guided Navigation component does not support multi-select for hierarchical dimensions, nor does it support tree view controls. Also, because aggregated records are not supported anywhere in the Discovery Framework, aggregated statistics are not supported in this component.

Dependencies

The Breadcrumbs component is required in order to view or clear Guided Navigation component selections.

The image below shows the interaction between the Guided Navigation, Breadcrumbs, and Results Table components. The navigation state, which is displayed in the Breadcrumbs component, determines what is displayed in the Results Table component. If the user navigated to a different state in the Guided Navigation component, the other two components would dynamically update to reflect the change.

Note: The Guided Navigation component supports the use of aggregated records. Specifically, when the component is using a data source with a rollup key specified, its refinements display the number of aggregated records. For details about configuring Discovery Framework data sources for aggregated records, see the Discovery Framework Installation Guide.

Note: In order for the Guided Navigation component to generate aggregated record refinement statistics, the --stat-abins flag must be enabled on the MDEX Engine.

Note: The Guided Navigation component includes a threshold on the maximum number of dimension values that can be displayed at once within a dimension. The default value is 500. This threshold is in place for performance and usability reasons, so that the end user's experience can be managed for cases where dimensions include very long lists of dimension values. This threshold can be used in conjunction with dynamic ranking and type-ahead search in the Guided Navigation interface, so users can still access specific values by filtering for them.
