Actually DrillSideways is independent of multi-select. Ie, it's useful to have the sideways counts for a drill-down field, whether your UI offers single or multi select for a given dimension. DrillSideways.java is a different implementation (minShouldMatch=N-1 query w/ custom collector to separate hit from near-miss) than Solr (tagging/excluding filters), and also a different interface.
