Class DrillDownQuery
A Query for drill-down over facet categories. You should call Add(String, String[]) for every group of categories you want to drill-down over.
NOTE: if you choose to create your own Query by calling
Term(String, String, String[]), it is recommended to wrap it with ConstantScoreQuery
and set the Boost to 0.0f,
so that it does not affect the scores of the documents.
