// EDITOR'S TAKE
Onyx is the closest match, pairing a large connector library with retrieval-augmented answers rather than raw keyword hits. Swirl Search is the option when you cannot move data and need federated queries instead, while Elasticsearch gives you a stronger engine but leaves connectors, ranking and question answering for you to build.
