Moises,

In addition to what others have stated, you will need to likely have a way to switch between the different indexes as needed. After the index tags have been created, you would use:

Set Order to NameOfTag

wherever it was needed. You might even build it into the header of a grid column so that the user can change the order that the records in the grid are displayed. It could also be a dropdown list or simply coded into the Click of a button.
