In a corpus where parents and children share an index, it is the lens that looks at the child side while the outer query talks about parents.</p> <h2 id="how-it-works"> How it works <a class="anchor" href="#how-it-works">#</a> </h2> <blockquote> <p>Engine note: the current implementation runs sub-aggregations over the scoped document set keyed by the relation; it does not resolve per-parent child sets.</p>
