title: Use polygon as search area overpass api / overpass turbo
body: <p>I'm fairly new at using overpass API, I finally managed to generate a query to retrieve all nodes within an area by using overpass-turbo wizard. </p>
  
  <p>Using <code>highway=* in "Paulino Navarro"</code> in the wizard generates me the following query.</p>
  
  <pre><code>/*
  This has been generated by the overpass-turbo wizard.
  The original search was:
  “highway=* in "Paulino Navarro"”
  */
  [out:json][timeout:25];
  // fetch area “Paulino Navarro” to search in
  {{geocodeArea:Paulino Navarro}}-&gt;.searchArea;
  // gather results
  (
    // query part for: “highway=*”
    node["highway"](area.searchArea);
    way["highway"](area.searchArea);
    relation["highway"](area.searchArea);
  );
  // print results
  out body;
  &gt;;
  out skel qt;
  </code></pre>
  
  <p>However, <strong>how could I use a polygon as a search area?</strong> maybe something like <code>highway=* in poly([lat,lon],[lat,lon],...,[lat,lon])</code> or how can I do that on the query itself.</p>
  
  <p>I don't quite understand the documentation in overpass wiki nor overpass-turbo wizard. </p>
