 | key | default value | description
 
 | opensearch.addresses | - | OpenSearch server address(es). An address without a scheme is contacted over plain http, on port 9200 if none is given; use `https://` when credentials are configured.
-| opensearch.user | - | Username for Basic authentication (optional). The credentials are only sent to the addresses listed, matched on scheme, host and port, not to nodes discovered by sniffing under another address; list those nodes in the addresses or disable `opensearch.<type>.sniff`, which is on by default. A warning is logged when sniffing is enabled together with credentials, and if an address other than a loopback one uses plain http.

 | opensearch.password | - | Password for authentication (optional).
-| opensearch.<type>.sniff | true | Discover the other nodes of the cluster and send requests to them as well. The nodes found are contacted over https if one of the addresses uses https, over plain http otherwise.
 | opensearch.disable.tls.validation | false | Do not check the certificates and host names of the OpenSearch nodes. A warning is logged when this is enabled.
 | opensearch.concurrentRequests | 2 | Number of concurrent bulk requests.
 | opensearch.indexer.index.name | content | Index name for crawled documents.
