The fix for issue #34 (Returning a result when only some of the requested c-codes were present, and some were not) was implemented in the middle tier because the terms query in Elasticsearch 5 doesn't provide a mechanism for requiring they all be present.
In Elasticsearch 7, the terms_set provides a mechanism for specifying a minimum number of matches. Using the minimum_should_match_script parameter would allow a script to require a minimum of the number of items being searched.
