    Constructors in org.apache.lucene.facet with parameters of type FacetsConfig
    Constructor and Description
    `DrillDownQuery(FacetsConfig config)` Creates a new `DrillDownQuery` without a base query, to perform a pure browsing query (equivalent to using `MatchAllDocsQuery` as base).
    `DrillDownQuery(FacetsConfig config, Query baseQuery)` Creates a new `DrillDownQuery` over the given base query.
    `DrillSideways(IndexSearcher searcher, FacetsConfig config, SortedSetDocValuesReaderState state)` Create a new `DrillSideways` instance, assuming the categories were indexed with `SortedSetDocValuesFacetField`.
    `DrillSideways(IndexSearcher searcher, FacetsConfig config, TaxonomyReader taxoReader)` Create a new `DrillSideways` instance.
    `DrillSideways(IndexSearcher searcher, FacetsConfig config, TaxonomyReader taxoReader, SortedSetDocValuesReaderState state)` Create a new `DrillSideways` instance, where some dimensions were indexed with `SortedSetDocValuesFacetField` and others were indexed with `FacetField`.
    `DrillSideways(IndexSearcher searcher, FacetsConfig config, TaxonomyReader taxoReader, SortedSetDocValuesReaderState state, ExecutorService executor)` Create a new `DrillSideways` instance, where some dimensions were indexed with `SortedSetDocValuesFacetField` and others were indexed with `FacetField`.
    `FacetQuery(FacetsConfig facetsConfig, String dimension, String... path)` Creates a new `FacetQuery` filtering the query on the given dimension.
    `MultiFacetQuery(FacetsConfig facetsConfig, String dimension, String[]... paths)` Creates a new `MultiFacetQuery` filtering the query on the given dimension.
