About this API
CloudSearch is AWS's search service launched in 2012, based on Solr. When Elasticsearch wasn't mainstream yet, it was a decent choice. But AWS launched Elasticsearch Service in 2015 (later renamed OpenSearch Service), making CloudSearch's position awkward — slow updates, far smaller community ecosystem than Elastic. New projects almost never choose CloudSearch anymore, but legacy customer apps still run, so the API isn't deprecated. Our recommendation: for new projects, use OpenSearch Service or dedicated search SaaS like Algolia/Typesense.
