Description: NameUsage and registry search can be simplified by moving some constants to a Solr request handler, for example in NameUsageSearchServiceImpl the code below can be replaced by invariants in a request handler:
PRIMARY_SORT_ORDER.put("score", SolrQuery.ORDER.desc);
    PRIMARY_SORT_ORDER.put("num_descendants", SolrQuery.ORDER.desc);
    PRIMARY_SORT_ORDER.put("scientific_name", SolrQuery.ORDER.asc);
    // Suggest default filters for suggest service: names of type INFORMAL and BLACKLISTED are excluded by default.
    SUGGEST_DEFAULT_FILTERS.put(NameUsageSearchParameter.NAME_TYPE, NOT_OP + NameType.INFORMAL.name());
    SUGGEST_DEFAULT_FILTERS.put(NameUsageSearchParameter.NAME_TYPE, NOT_OP + NameType.BLACKLISTED.name());

The shards parameter could be moved to a request handler, and possibly all the weights associated to fields can be moved to a request handler too, for example:
 @FullTextSearchField(field = "canonical_name", exactMatchScore = 100.0d,
      partialMatchScore = 1d, partialMatching = WildcardPadding.RIGHT),
    @FullTextSearchField(field = "vernacular_name", highlightField = "vernacular_name_lang", exactMatchScore = 10d,
      partialMatchScore = 0.75d, partialMatching = WildcardPadding.RIGHT),
    @FullTextSearchField(field = "scientific_name", exactMatchScore = 5d,
      partialMatchScore = 0.7d, partialMatching = WildcardPadding.RIGHT),
    @FullTextSearchField(field = "description", exactMatchScore = 0.2d,
      partialMatching = WildcardPadding.NONE)
