Index in your program it just like you would a table. Just know that the index is not persistent from application use to application use. If you index it right on opening the view, the index will remain as long as the view is open. Close the view, and you have to re-create the index when you open it again.

If you set it's NODATAONLOAD property to .T. before when you first open it, then create the index, and then requery it, the indexing time is negligable.
