Good evening.
How to implement so that when prompting Yandex in the search field, only Russian CITIES fall out?
Here is an example code:

var myMap = new ymaps.Map('map', {
            center: [60.906882, 30.067233],
            zoom: 9,
            type: 'yandex#map',
            controls: []
        }),
        search = new ymaps.control.SearchControl({
            options: {
                useMapBounds: true,
                noPlacemark: true,
                noPopup: true,
                placeholderContent: 'Адрес',
                size: 'large'
            }
        }),

Thank you very much in advance!
