그림과 같이 한계 매개 변수를 사용하는 것이 가장 좋은 방법입니다. 기본값은 20 곳이지만, 그것은 또한 편안하고 장소 API에 액세스하는 결과 집합에 묻혀 다음 URI,이 100

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

로 확장 할 수 있지만이있을 나타나지 않습니다 2.2.3 API에서 해당 데이터를 처리하기위한 모든 공용 함수.

가 여기에 API 탐색기 예에 따라 완벽하게 동작하는 예제입니다 : http://developer.here.net/apiexplorer/examples/api-for-js/places-search/places-search-by-category.html
