-On Elastic Cloud, you do not need to configure any settings to use Enterprise Search in {kib}. It is enabled by default. On self-managed installations, you must configure `enterpriseSearch.host`.
-
-`enterpriseSearch.host`::
-The http(s) URL of your Enterprise Search instance. For example, in a local self-managed setup,
-set this to `http://localhost:3002`. Authentication between {kib} and the Enterprise Search host URL,
-such as via OAuth, is not supported. You can also
-{enterprise-search-ref}/configure-ssl-tls.html#configure-ssl-tls-in-kibana[configure {kib} to trust
-your Enterprise Search TLS certificate authority].
-
-
-`enterpriseSearch.accessCheckTimeout`::
-When launching the Enterprise Search UI, the maximum number of milliseconds for {kib} to wait
-for a response from Enterprise Search
-before considering the attempt failed and logging a warning.
-Default: 5000.
-
-`enterpriseSearch.accessCheckTimeoutWarning`::
-When launching the Enterprise Search UI, the maximum number of milliseconds for {kib} to wait for a response from
-Enterprise Search before logging a warning. Default: 300.
