Is it possible to use Semantic Drilldown (or another extension) to select
wikipages via categories when each page belongs to multiple categories? For
example, a page belonging both to TECH and MEDICAL categories could be
found by clicking on TECH and then MEDICAL or vice versa. I believe this
approach is called faceted search. I'd like to get this working without
Cargo or semantic markup if possible--just good old-fashion categories.
