In my experience, the care and feeding that goes into an Elastic Search cluster feels like it's often substantially higher than that involved in the primary data store, which has always struck me as a little odd (particularly in cases where the primary data store is an RDBMS).
I'd be very happy to use simpler more bulletproof solutions with a subset of ES's features for different use cases.
