When retrieving events via the api if the query variables include $top => 10 and 'idsOnly' => 'true', should this only return 10 Ids or does the 'idsOnly' argument only return the Ids of all the events? I am finding that it observes the $filter arguments but not the $top number of events to return. Now if I don't include idsOnly (or set it to false), it observes the $top variable and returns the number of events specified.
