Geocode an Address within a Bounding Box probably not working properly?

I am trying to understand how exactly bounding box is working, but from my tests at the moment it seems that result is returned regardless of the bounding box limits.

I tried various approaches,but it appears that either the flow is working this way or I am missing something. In short, I have tried to put in example request: https://developer.here.com/api-explorer/rest/geocoder/latitude-longitude-by-mapview-parameter mapview in Boston suburban area and search text which is my home address in Bulgaria - few thousand miles away from the bounding box borders. However, I still get a result-my address Geocoded correctly. Since it is out of the bounding box I was expecting either 0 results or some exception. Or there is some parameter in the Response I can use for defining outboxing-for this case that might be the Distnace because I am too far but in addresses close to borders I am not sure if that will be fine.

My URL request: https://geocoder.api.here.com/6.2/geocode.json?searchtext=g.k.%20Krasna%20polyana%201%2022%D0%91%2C%201373%20g.k.%20Krasna%20polyana%201%2C%20Sofia&mapview=42.3902%2C-71.1293%3B42.3312%2C-71.0228&gen=9&app_id=devportal-demo-20180625&app_code=9v2BkviRwi9Ot26kp2IysQ

The result I got:

                  }
                ]
              }
            }
          }
        ]
      }
    ]
  }
}'

I am expecting some standard way to catch the results out of the bounding box. Actually, it seems that either there is no clear value to count on or I am missing something about the way it works. Thanks in advance!
