Custom Fields Search in Frontend New Feauture

[niosme]

Its nice that virtuemart have filter options on top by custom fields. But it should be better when a combination of custom fields dont exist then hide or disable those custom field option that will lead to an empty resutl page.
When someone press a combination at 80 percent of situations is going to a page with no products.

Also when is a clear number in filter always throw empty results by fault.

Will this be added in a future version?
Thanks in advance. I can help on that also!
