markus,

It was never the goal to reach full optimization. I did just check the influence of the deleted tag in a rushmore optimizable (partual) expression, and it was about none.

This just means that even if you reach full optimization it would run just as fast as the same query but without the index on DELETED()

But for the record, i'll check this.

Walter,
