// EDITOR'S TAKE

Elasticsearch and OpenSearch come closest on scale and ranking control, but they are engines rather than products, so connectors, relevance tuning and the search UI are your job. Swirl Search is the only one here that mirrors Coveo's federated connect-to-everything approach, while Typesense and Meilisearch are the fastest path to good site search when enterprise breadth is not the point.
