As per [our discussion during the F2F|https://docs.google.com/document/d/16PAa__LsxyLZcbW3q1MvgyIznh4ZnCYLupbNMXKMRds/edit?pli=1#heading=h.esav1agqdszh] We would use to Elasticsearch's [ " missing_value null_value " |https://www.elastic.co/guide/en/elasticsearch/reference/current/null-value.html] concept, and something similar in the Lucene backend. Note this does not mean we give up the concept of "exists"/"missing" queries predicates (HSEARCH-2464) . We will handle that separately. |
