, MongoDB\Driver\Query $query
[, MongoDB\Driver\ReadPreference $readPreference
] )

The
readPreferenceparameter does not control the server to which the driver issues the query; the query will always be executed on this server object. Instead, it may be used when issuing the command to a secondary (from a replica set connection, not standalone) or mongos node to ensure that the driver sets the wire protocol accordingly or adds the read preference to the query document, respectively.
