MongoDB\Driver\Server::executeQuery
  Execute a database query on this server
  
 
  Description
  
   final public MongoDB\Driver\Cursor MongoDB\Driver\Server::executeQuery(string $namespace, MongoDB\Driver\Query $query, arraynull $options = null)
  
  
   Default values for the "readPreference" option and Query's
   "readConcern" option will be inferred from an active
   transaction (indicated by the "session" option), followed
   by the connection URI.
  
  
  Note: 
   
    The "readPreference" option does not control the server
    to which the driver issues the operation; it will always be executed on
    this server object. Instead, it may be used when issuing the operation 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 operation, respectively.
