Yes, this is exactly what FUSE Search does. We have some clients that use FUSE for a single source, which is fine, but where FUSE shines is by connecting to many content sources and unifying results in one spot. You may wonder what faceted search is (sometimes this gets interchanged with federated). Facets = filters. And, yep, FUSE excels here too - better than any other offering you’ll find.
