 This is a [plugin](https://arc.codes/docs/en/guides/plugins/overview) for [Architect](https://arc.codes/) that provisions managed [Amazon OpenSearch](https://aws.amazon.com/opensearch-service/) for the application.
 
-When you are using Architect's [sandbox](https://arc.codes/docs/en/reference/cli/sandbox) mode, the plugin [downloads and runs Elasticsearch](https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html#elasticsearch-install-packages) or [OpenSearch](https://opensearch.org/downloads.html#opensearch) locally.

If search engine binaries are not available for your platform, then the plugin falls back to trying to launch them in a container using [Docker](https://www.docker.com).
 
 Pair this pacakge with [@nasa-gcn/architect-functions-search](https://github.com/nasa-gcn/architect-functions-search) to connect to the service from your Node.js Lambda function code.
