Sådan bruger du MongoDB GeoSpatial Index i C++

Du kan bruge <0> options::find::limit . Tjek også . Følgende burde virke:

mongocxx::options::find opts;
opts.limit(10);

mongocxx::cursor cursor = coll.find(document{} << "loc" << open_document 
    << "$near" << bsoncxx::builder::stream::open_array 
    << lon << lat << bsoncxx::builder::stream::close_array 
    << close_document << finalize, opts);
