Queries use Pizza&rsquo;s <a href="https://pizza.rs/docs/references/api_convention/#canonical-query-syntax-and-elasticsearch-tolerance">canonical DSL</a>, and the results are engine-level output (no gateway envelope: no <code>_key</code>, <code>_shards</code> or <code>_collection</code> wrappers; the engine&rsquo;s <code>parsed_query</code> plan string appears only behind the result panel&rsquo;s debug 🐛 toggle).</p> <p>Flip the editor to <strong>SQL</strong> to run SELECT statements through the engine&rsquo;s <a href="https://pizza.rs/docs/references/sql/">SQL frontend</a> — the same parse/lower/shape path the <code>/_sql</code> gateway wire rides. The example chips load per-dataset statements covering the subset (filters, <code>MATCH</code>/<code>SCORE()</code>/<code>HIGHLIGHT</code>, <code>KNN</code>, <code>CASE</code>, scalar functions, <code>GROUP BY</code> with <code>DATE_TRUNC</code>/<code>HISTOGRAM</code> bucketing, <code>COUNT(DISTINCT)</code>, <code>$1</code> parameters, an <code>EXPLAIN</code> chip showing the compiled DSL plan — and one deliberately rejected statement to show a positioned plan error). SQL answers render as the gateway&rsquo;s frozen <code>columns</code>/<code>rows</code> envelope — a typed table, with a raw JSON view one click away. The <strong>composite cursor walk</strong> chip shows keyset paging: a full grouped page hands back a cursor, and <em>Next page</em> resubmits the identical statement with it — exactly what <code>/_sql</code>&rsquo;s <code>cursor</code> request field does.</p>
