> Suppose the following facet values tree:
> Facet
>  - V1
>  -- V1.1
>  -- V1.2
>  -- V1.3
>  -- V1.4
>  -- (not topK values)
>  - V2
>  -- V2.1
>  -- V2.2
>  -- V2.3
>  -- V2.4
>  -- (not topK values)
> Use case:
> 1 - select V1 => all V1.x are selected
> 2 - de-select V1.1
> The implementation of the negation of value V1.1 is missing in DrillDownQuery, it would be nice to implement it.
