A query that rewrites into another query using JoinUtil.createJoinQuery(String, Query, Query, IndexSearcher, ScoreMode, MultiDocValues.OrdinalMap, int, int) that executes the actual join. This query is exclusively used by the HasChildQueryBuilder and HasParentQueryBuilder to get access to the DirectoryReader used by the current search in order to retrieve the MultiDocValues.OrdinalMap. The MultiDocValues.OrdinalMap is required by JoinUtil to execute the join.
