title: bbox not restrict search results
body: <p>I'm reviewing HERE API, and I can't figure this issue:
  I'm interesting in <code>Geocoder</code> API, and I tried the following query:</p>
  
  <p><code>http://geocoder.cit.api.here.com/6.2/geocode.json?
  &amp;app_id=***
  &amp;app_code=***
  &amp;searchtext=london
  &amp;bbox=41.9085286,-87.6762943;41.8682739,-87.6041965
  &amp;gen=8</code></p>
  
  <p>The bonding box I defined is around Chicago USA, so I expect to get no results.
  But the response contains London information and I cant figure why.</p>
  
  <p>I read <a href="https://stackoverflow.com/questions/20600367/why-are-search-results-not-limited-to-the-bounding-box">in this question</a> that If I use the <code>landmark</code> request the <code>bbox</code> is not always taken into consideration.
  But here i'm using <code>geocode</code> requirest.</p>
