This is a nightmarish recommendation. Totally get elastic trying to branch out but there are hard (even mathematical) limitations on what a single DB can and should do. The only DB that's presented me with a semi coherent theory about how it should be used as a swiss army knife is Datomic and I would be very skeptical of it at large scales. Also it's based on Prolog and inspired by algebraic DB concepts so is just way outside the mainstream. Elastic search is really convenient for faceted search, so I think it should just stick to that.
