It turns data gaps into a number you can alert on, instead of discovering them when a report quietly undercounts.</p> <h2 id="how-it-works"> How it works <a class="anchor" href="#how-it-works">#</a> </h2> <p>For every document the query matched, the engine checks whether the field has an indexed value in the column store — an absent field and an explicit <code>null</code> both count as missing. The matching documents form one bucket shaped <code>{ &quot;doc_count&quot;: N, …sub-aggs }</code>; sub-aggregations run over exactly those incomplete documents, so you can ask not just how many rows are broken but how they break.</p>
