HERE Maps matchLevel parameter not working - here-api

Question

I am trying to filter only cities in HERE Map's autocomplete API. I read on their documentation that there is matchLevel parameter...
However, nothing changes if I include it.
This is my call:
http://autocomplete.geocoder.api.here.com/6.2/suggest.json?app_id=MY_APP_ID&app_code=MY_APP_CODE&matchLevel=city&query=New York
I still get responses which are not city type.
{
"suggestions": [
{
"label": "United States, New York",
"language": "en",
"countryCode": "USA",
"locationId": "NT_rNsDLtnazM.kjVC-K6YWOA",
"address": {
"country": "United States",
"state": "New York"
},
"matchLevel": "state"
},
{
"label": "United States, New York, New York, New York",
"language": "en",
"countryCode": "USA",
"locationId": "NT_YpQcXqbaOb.I4m5EW8BHEC",
"address": {
"country": "United States",
"state": "New York",
"county": "New York",
"city": "New York",
"postalCode": "10007"
},
"matchLevel": "city"
},
{
"label": "United States, New York, New York",
"language": "en",
"countryCode": "USA",
"locationId": "NT_ABhedB4xGEL83YY5az47iD",
"address": {
"country": "United States",
"state": "New York",
"county": "New York"
},
"matchLevel": "county"
},
...
Any help is appreciated.

Answer 1

matchLevel is a response field, not a query parameter.
use postprocessing of the answer, like array.filter() to keep only elements of the answer which match "city"
