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

Indices return candidate lists for a filter component
which may contain entries which do not the filter component.
Hence, the 'not' of the candidate list may not contain all
of the entries which do match the not of the filter component.
The error is to assume otherwise.

Your test attempts to improve the pres index (and as such
may be worthy of inclusion), but it clearly doesn't address
the underlying design issue regarding index application and
the not operator.

Well, as you argue, it's not acceptable to have only a
subset of the matched entries returned.
