Doesn't elastic search require a decent size server just to run with no data? Curious about the costs of running elastic search for a small number of documents compared to the low cost of running django. For example the frontend could be static and hosted on S3 for pennies while elastic search seems to recommend at least 8 GB of ram which would be $40/mo on some lost cost VPS providers. Pretty big price difference for a smaller site with a small record set that wants a fast search experience.
