The idea w/ drill down is you are running a "base query" (what the user actually searched for, originally) and then, if the user has clicked to drill down on any facet labels, you are also adding drill-down queries.
You pass the "base query" to the DrillDownQuery constructor. And, normally, to add drill-down queries, you would use the add method that takes only strings, when the user clicked on a dimension + label. The add method that takes a custom drill-down query is for more advanced use cases, where you are able to create your own query that accomplishes the same thing as drilling down by a label; e.g., for numeric range facets, you would use this method to pass a numeric range filter down. Have you seen the demo facet examples, e.g. https://github.com/apache/lucene-solr/blob/master/lucene/demo/src/java/org/apache/lucene/demo/facet/SimpleSortedSetFacetsExample.java ? Are you using SSDV facets or taxonomy facets?
