Examples of DrillDownQuery

org.apache.lucene.facet.DrillDownQuery
A {@link Query} for drill-down over facet categories. Youshould call {@link #add(String,String)} for every group of categories youwant to drill-down over.
NOTE: if you choose to create your own {@link Query} by calling{@link #term}, it is recommended to wrap it with {@link ConstantScoreQuery}and set the {@link ConstantScoreQuery#setBoost(float) boost} to {@code 0.0f}, so that it does not affect the scores of the documents. @lucene.experimental
org.apache.lucene.facet.search.DrillDownQuery
A {@link Query} for drill-down over {@link CategoryPath categories}. You should call {@link #add(CategoryPath)} for every group of categories youwant to drill-down over. Each category in the group is {@code OR'ed} withthe others, and groups are {@code AND'ed}.
NOTE: if you choose to create your own {@link Query} by calling{@link #term}, it is recommended to wrap it with {@link ConstantScoreQuery}and set the {@link ConstantScoreQuery#setBoost(float) boost} to {@code 0.0f}, so that it does not affect the scores of the documents. @lucene.experimental
