In HSEARCH-1872 In Progress , a sort DSL is being introduced. This DSL will have to be extended with elements that were excluded from the initial work:

• a withComparator() method for building a sort that will use a java.util.Comparator
• a treatMultiValuedAs(mode) method for instructions about how multi-valued fields should be sorted.
• a byNative() method for injecting implementation-dependent sorts inside a DSL-built sort (such as a JSON string for ElasticSearch, or a SortField for a local Lucene index)
