I think I'm not understanding your post. Unless this is a requirement of the specific application, why would zero or blank not be a valid index? Zero and blank are just characters. I regularly have indexes with zeroes and blanks for some vales.

I'm reviewing the suggestions provided by the Index Advisor and some of
the key fields suggested are often blank or zero. Assuming blanks or zeros
aren't valid index entries, should I create my indexes with WHERE clauses and
exclude zeros/blanks?
