How is faceted navigation different from hierarchical navigation?


Asked by Kairi Conley on Dec 08, 2021 FAQ



In contrast to hierarchical navigation based on only one attribute, faceted navigation offers users the ability to navigate to desired items based on several attributes. In addition, users can select any available attribute to start their navigation. Another important benefit is that an empty result set is not possible with faceted navigation.
And,
If you're new to search development, the best way to think of faceted navigation is that it shows the possibilities for self-directed search. It's a type of drill-down search experience, based on predefined filters, used for quickly narrowing down search results through point-and-click actions.
In fact, In Azure Cognitive Search, faceted navigation is built at query time, using fields that you previously attributed in your schema. In the queries that your application builds, a query must send facet query parameters to get the available facet filter values for that document result set.
Also Know,
Faceted navigation is thus more flexible and more useful than systems which provide only one or two different types of filters, especially for extremely large content sets.
Besides,
Faceted navigation and sorting are more sought-after query refinement tools than related searches, but are a bit more difficult to achieve unobtrusively. The first decision that must be made is whether faceted navigation or sorting should be provided on the primary search screen or whether they should have a dedicated view of their own.
