Re: Indexed searches which contain a NOT filter return incomplete results (ITS#1405)

[klb@paradyne.com]

So if I have an application that uses "not" on attribute "x", it will work
if indexes are not defined for "x" but will not work correctly if indexes are
defined?

If so, this needs to be documented in very large print at the
top of the discussion about adding indexes.

Do you have any idea if this restriction applies to iPlanet?

Thanks!
