org.apache.lucene.facet.index.params.DefaultFacetIndexingParams
Default implementation for {@link FacetIndexingParams}.
Getters for partition-size, {@link OrdinalPolicy} and{@link PathPolicy} are all final, and so the proper way to modify them whenextending this class is through {@link #fixedPartitionSize()}, {@link #fixedOrdinalPolicy()} or {@link #fixedPathPolicy()} accordingly. @lucene.experimental
