How to get data from a marker on a Yandex Maps map?

Question

JavaScript

function init() {
    var myMap = new ymaps.Map('map', {
        center: [55.74, 37.58],
        zoom: 13,
        controls: []
    });
    var searchControl = new ymaps.control.SearchControl({
        options: {
            provider: 'yandex#search'
        }
    });
    myMap.controls.add(searchControl);
    searchControl.search('Шоколадница');
}
ymaps.ready(init);

An example from the documentation https://tech.yandex.ru/maps/jsbox/2.1/search_contr...
I am searching for some organizations and display icons on the map.
1. How can I change the image of found tags?
2. How can I get data when clicking on the found label?
