docs: Search for entries inside a given area defined by the two extreme points of a rectangle.
  At indexing, you should specify geoloc of an object with the _geoloc attribute (in the form "_geoloc":{"lat":48.853409, "lng":2.348800} or
  "_geoloc":[{"lat":48.853409, "lng":2.348800},{"lat":48.547456, "lng":2.972075}] if you have several geo-locations in your record).
  <p>
  You can use several bounding boxes (OR) by calling this method several times.
