elasticsearch\Connection $nodes

The elasticsearch cluster nodes to connect to.

This is populated with the result of a cluster nodes request when $autodetectCluster is true.

Additional special options:

• auth: overrides $auth property. For example:

[
 'http_address' => 'inet[/127.0.0.1:9200]',
 'auth' => ['username' => 'yiiuser', 'password' => 'yiipw'], // Overrides the `auth` property of the class with specific login and password
 //'auth' => ['username' => 'yiiuser', 'password' => 'yiipw'], // Disabled auth regardless of `auth` property of the class
]

• protocol: explicitly sets the protocol for the current node (useful when manually defining a HTTPS cluster)
