title: Amazon ItemSearch API reponse different from amazon.com search results
body: <p>I am trying to figure out the right parameters for ItemSearch such that the API call will return the same result as on the website. Currently I am using these params it is not consistent with the website.</p>
  
  <pre><code>url_params = dict(
          Service='AWSECommerceService', 
          Operation='ItemSearch', 
          AssociateTag=AMAZON_ASSOCIATETAG,
          SearchIndex='All',
          AWSAccessKeyId=AWS_ACCESS_KEY_ID,  
          Keywords=keywords,
          ResponseGroup='Small,OfferSummary,Images'
          )
  </code></pre>
  
  <p>For example if 'iphone%205s' is put in keywords, the API returns a list of iPhone protectors, while searching on the website gives iPhones as top results.</p>
