Examples of OrdinalPolicy

org.apache.lucene.facet.index.categorypolicy.OrdinalPolicy
Filtering category ordinals in {@link CategoryParentsStream}, where a given category ordinal is added to the stream, and than its parents are being added one after the other using {@link TaxonomyWriter#getParent(int)}.
That loop should have a stop point - the default approach (excluding the ROOT) is implemented in {@link DefaultOrdinalPolicy}. @lucene.experimental
