Needs better example to have to extract Facet Data in Java SDK 3.x

Map<String, SearchFacet> facets = new HashMap<>();

facets.put("categories", SearchFacet.term("category", 5));

SearchResult result = cluster.searchQuery(

  "index",

  SearchQuery.queryString("query"),

  searchOptions().facets(facets)

);

        for (SearchFacetResult sfr : result.facets().values()) {

            System.out.println("facet_field: " + sfr.field());

            List<SearchTermRange> tsfRange = ((TermSearchFacetResult) sfr).terms();

            for (SearchTermRange tsfr: tsfRange) {

                System.out.println(tsfr.name() +": " + tsfr.count());

            }

        }
