>From what I understand, they do the following: - each facet group offer the list of facets and the number of elements in each facet as if none of the facet for that group is selected. - if a given facet group A has some facets selected, then the other facet groups and their facet list and numbers are filtered by the facet group A.
That's consistent to me and what I would expect intuitively before thinking about implementation details. They also allow to select multiple facets for a given facet group but that's an orthogonal story.
