>"However this index is useless"! This information is completely wrong!!! A binary index tag on deleted() can speed up your queries a lot, unlike orinary index tag on deleted() in previous versions of VFP. But I expect you to deny this statement. (Sigh in advance!)

I tend to think of an index on deleted() more likely to be harmful than helpful - what sort of improvements have been made in recent versions?
