How do I use and interpret facets with the search REST API?
Oracle Service Cloud Knowledge Advanced Search REST API
The search REST API /question endpoint returns a results list along with facets that are associated with that list, and each question returns results with only the next level of facets and not the sub-facets of those.
- The facets can only be selected one at a time in a tree, so 1 product, 1 category, 1 collection, 1 doc type.
- The next level of facets returned will only be for the specified facets in the question.
- There is not sub-facet information for a Collection filter.
- Facets will be returned that are relevant to the content returned, so 1 search may return 5 children while another only returns 2. Or when I use CMS-PRODUCT as the filter, i get 7 different PRODUCT facets, and 6 collections and none of them show me the children because none of them are selected
- In some cases you might have to drill down 2-3 levels of a facet to get to the leaf children, where the actual assignment are, because the parents are inherited, rather than assigned.
