Current thinking is to try and limit what sort of Facet integrations we support (EG: no Geolocation) in the hopes that if you switch services in the future, you won't lose functionality.          |
-| Multi-search                                                | No             | If desired            | Not supported by many search services. It wouldn't be unreasonable effort to add this functionality though. Plugin modules for services without mult-search could manually perform 2 searches and combine the results.                                    |

This feature in particular is an example of the "silent treatment" that might be applied when a feature disappears between service providers. |
