org.elasticsearch.index.search.child.ChildrenQuery
A query implementation that executes the wrapped child query and connects all the matching child docs to the related parent documents using {@link ParentChildIndexFieldData}.
This query is executed in two rounds. The first round resolves all the matching child documents and groups these documents by parent uid value. Also the child scores are aggregated per parent uid value. During the second round all parent documents having the same uid value that is collected in the first phase are emitted as hit including a score based on the aggregated child scores and score type.

        BitDocIdSetFilter parentFilter = parseContext.bitsetFilter(parentDocMapper.typeFilter());
        ParentChildIndexFieldData parentChildIndexFieldData = parseContext.getForField(parentFieldMapper);


        Query childrenQuery;
        if (minChildren > 1 || maxChildren > 0) {
            childrenQuery = new ChildrenQuery(parentChildIndexFieldData,  parentType, childType, parentFilter,query,ScoreType.NONE,minChildren, maxChildren, shortCircuitParentDocSet, nonNestedDocsFilter);
        } else {
            childrenQuery = new ChildrenConstantScoreQuery(parentChildIndexFieldData, query, parentType, childType, parentFilter,
                    shortCircuitParentDocSet, nonNestedDocsFilter);
        }
        if (filterName != null) {
