title: Aloglia: Index circle location zone for geo-search
body: <p>Is it possible to index a circle zone and make it work with Algolia geo-search.</p>
  
  <p>The only solution I can come with is to index multiples points of the circle like that :</p>
  
  <pre><code>"_geoloc": [
    { "lat": 47.279430, "lng": 5.106450 },
    { "lat": 47.293228, "lng": 5.004570 },
    { "lat": 47.316669, "lng": 5.016670 }
  ]
  </code></pre>
  
  <p>But I think it wont be very accurate unless I have a lot of points. Any thoughts ?</p>
