    discover/here is returning an empty list

    Hi,

    When using the REST API, it seems that discover/here sometimes returns an empty list while discover/explore for the same coordinates return a list. Could someone explain why this is the case? Is it expected? Should I rather use explore than here?

    As an example (replace the app_id and app_code with your own values), this returns a list of places:
    http://places.nlp.nokia.com/places/v...&app_code=XXXX

    This returns an empty list:
    http://places.nlp.nokia.com/places/v...&app_code=XXXX

    Thanks

    Re: discover/here is returning an empty list

    Places API provides three different resources that try to answer three different user questions:

    explore: "what's popular nearby?"
    here: "where am I?"
    around (still experimental): "what places are around me?"

    Based on that "here" only returns places very close to the search center. "explore" and "around" instead takes by default a much larger search readius into account, but have a fundamental difference how certain place attributes influence the ranking. (much simplified: "explore" uses primarily popularity; for "around" the distance weights much more)

    You should choose the resource that best fits the use case your app wants to support.

    Hope that helps,
    Andreas
