// EDITOR'S TAKE

OpenSearch is the literal drop-in, a fork that keeps the same APIs and query language under Apache 2.0, so migrations are mostly a config change. If you only need product or site search, Meilisearch and Typesense are dramatically simpler to operate with typo tolerance built in, and Quickwit is the cheaper option for log search backed by object storage.
