Description

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.
