How can I displayed as sum (aggregated) values on distincted records?


I have problem with show filters after using distinct and facetingAfterDistinct option on true. If I enabled these options I don’t see filters (facets) that didn’t return in search query. Sometimes I have wrong value of filters counters, but its works when I use search . Is possible show all filter values, not only returned after query execute? Why I have different value of filters counters when I use filters and search box panel ? Maybe I should be used multi indices ?

I use distinct by OfferNumber attribute and sort by Price attribute.
