Facets with 0 Count

Hi All, 

I am using Episerver Find and want to show all Facets, including those with a 0 count. 

I have tried using the AllTerms = true although this seems to limit the number of Facets Items to 10. When using Size = x option when filtering the Facets seems to get filtered out. I cant use AllTerms and Size togeather. 

FilterHits has no effect on the Facets. 

What I am ideally looking for is a way to use AllTerms and Size togeather

Thanks
