more than 20 results in nokia map 'nokia.places.search.manager.findPlaces' function?

Question

It looks like your best bet at the moment would be to use the limit parameter as shown. The default is 20 places, but it can be extended to 100.

 searchManager.findPlacesByCategory({
        category: category,
        onComplete: processResults,
        searchCenter: searchCenter,
        limit: 50,
    });

There is also a next URI buried in the result set, which accesses the RESTful Places API, but there doesn't appear to be any public function for processing that data yet in the 2.2.3 API.

Here is a fully working example based on the API Explorer example: http://developer.here.net/apiexplorer/examples/api-for-js/places-search/places-search-by-category.html

You need to obtain your own free app id and token to get it to work.
