I am not sure. But I think the index will be used anyway (which isn't always appropriate - see my FAQ), because the implicit condition, if you have SET DELETED ON, is ... AND NOT DELETED(). In other words, the index tag exactly matches the expression.

If you need your index for other purposes (besides "optimization"), there are ways to avoid VFP using it.

Hilmar.
