Additional description

• The following doesn't compile:

  List<Employee> employees = session.Query<Employee>()
      .Where(x => x.FirstName == "Anne")    
      .Statistics(out QueryStatistics stats) 
      .ToList();
  

  Had to modify the code to:

  List<Employee> employees = session.Query<Employee>()
      .Statistics(out QueryStatistics stats) // Call 'Statistics' before 'Where'
      .Where(x => x.FirstName == "Anne")    
      .ToList();
