Mike,

If you are interested (which I am sure you are) I have written a complete index tester program that I use on all our systems.

I was at the conference when Doug made the statement that it is easier to rebuild the indexes than to test them but with multiuser 24/7 systems I found it necessary to first confirm if there is an index problem before shutting the system down to rebuild the necessary indexes.
