We had a search functionality requirement in one of the projects and that’s how I got to know about Amazon OpenSearch Service, It provides a quick, relevant search experience and makes it easier to add a search feature to your applications.

The only hiccup is sizing the OpenSearch is a tricky and long-term process, and it often takes many iterations to make sure that you get the right specifications according to your workload. It also needs monitoring so as to be aware of future problems.
